In this article, a Bayesian estimator for a target position report is proposed. It is based on a maximum a priori algorithm, where the user's device knowledge about its location is used to deduce the prior probability density function. The algorithm does not require knowledge about the signal and noise levels, meaning, noninformative priors are used. It is well known that with a higher number of antenna

There have been frequent invasions of consumer-level micro unmanned-aerial-vehicles (MUAVs) against some important protected objects and places in megacities in recent years. How to deal with the threats of such low-slow-small (LSS) invaders has become a significant worldwide problem. This article analyzes the necessity of developing anti-MUAV technologies and constructing anti-MUAV systems in megacities

Millimeter-wave (mmWave) radar, as an emerging technique, is increasing in popularity for human activity recognition. In contrast to traditional sensors and radars, mmWave radars give detailed information on objects from the range domain to the Doppler domain. The short wavelength allows mmWave radars to achieve a high resolution and a small antenna size, but also makes them prone to noise. In this

Probability models are emerging as a promising framework to account for “intelligent” behavior. In this article, probability propagation is discussed to model agent's motion in potentially complex grids that include goals and obstacles. Tensor messages in the state-action space (due to grid structure, states are 2-D and the concomitant probability distributions are represented by 3-D arrays), propagated

Small satellites have revolutionized the space industry because of their variety of benefits over large satellites. Antennas are one of the key components of the small satellites, whose performance is very crucial for the overall performance of the satellite-based wireless systems. The stringent requirements of modern small satellites, such as the small size and mass, low-power, low-loss, and low-cost

The subject of this column is a quite remarkable German aircraft from World War II (WW2): the Horten Ho-229. This was a single-seat fighter/bomber aircraft with a steel and laminated plywood airframe, powered by two turbojet engines, and designed and built by the Horten brothers, Walter and Reimer. Its maximum speed was close to 1000 km/h. It looks for all the world like a modern-day stealth aircraft

Flight simulators based on wrap-around displays provide an immersive experience for pilot training, but not only are they expensive and bulky, they typically only simulate a single aircraft configuration. Virtual reality (VR) is an interesting alternative, providing an immersive experience with lower cost and space requirements, as well as the ability to simulate arbitrary aircraft. Unfortunately,

This article deals with state estimation of nonlinear stochastic dynamic systems. The stress is laid on general introduction of the selected estimation methods, description of their application in navigation systems, and treatment of the error sources in the navigation systems design.

The market for remote sensing space-based applications is fundamentally limited by up- and downlink bandwidth and onboard compute capability for space data handling systems. This article details how the compute capability on these platforms can be vastly increased by leveraging emerging commercial off-the-shelf (COTS) system-on-chip (SoC) technologies. The orders of magnitude increase in processing

Due to the COVID-19 pandemic, the situation at the international level is critical. COVID-19 is a type of pneumonia due to a coronavirus family. Due to this situation, like many countries, the Peruvian government has decreed mandatory social isolation, which was in effect through June 30, 2020. According to this decree, people were to stay at home and only go out to cover basic needs. After more than

360-degree video synthetic aperture radar (VideoSAR) presents a powerful capability for the information perception of dynamic scenes. In comparison to time-consuming airborne SAR, miniature SAR (MiniSAR) mounted on an unmanned aerial vehicle platform is a cost-effective configuration that provides a higher operation flexibility for video acquisition. Nevertheless, MiniSAR system development and signal

The articles in this special issue focus on the applications supported by quantum radar. QUANTUM physics has had a large impact on our everyday life. Relevant examples range from transistors and Monolithic microwave-integrated circuit, or MMIC,1 that make most of our technological society, as well as to nuclear energy, and to the science of materials. Some of these technologies have met with indisputable

We compute the minimum cost for an optimal quantum radar, and we compare it with the cost of actual real world classical radars as a function of range. Our calculations show that the minimum cost quantum radar at X-band is many orders of magnitude more expensive than the corresponding classical radar, even assuming the most optimistic wideband-phased array radar architecture. We also assume that the

Quantum illumination (QI) promises unprecedented performances in target detection, but there are various problems surrounding its implementation. Where target ranging is a concern, signal and idler recombination forms a crucial barrier to the protocol's success. This could potentially be mitigated if performing a measurement on the idler mode could still yield a quantum advantage. In this article,

It has been recognized for over half a century that quantum mechanics defines the ultimate limits for sensing devices, and products of that recognition are now on the horizon of practical implementation. One of the most promising of those products is quantum radar, which offers a capability to significantly improve the tradeoff between energy and detection sensitivity compared to classical alternatives

Quantum illumination has been suggested as a way to improve the sensitivity of remote target detection by taking advantage of quantum entanglement between a traveling electromagnetic beam of light interrogating the target, and a second beam kept in the lab. In the microwave domain, superconducting quantum circuit utilizing superconducting Josephson tunnel junctions can be used as quantum-limited amplifiers

A special class of noise radar that conforms to a frequency modulated (FM) structure has experienced a surge in practical applications in recent years. This article provides a historical context for these random FM waveforms, examines their useful attributes and associated trade-offs, and discusses some of these recent applications.

Classical radars use deterministic waveforms, such as linear frequency modulated pulses. Noise radars, on the other hand, use random waveforms, or waveforms that resemble random signals. The randomness of the signal provides certain advantages, such as limiting or avoiding range/velocity measurement ambiguity, or better resistance to jamming. This, however, comes at a price of more complicated system

With an increasing demand for high-resolution radar and wideband communication systems, the frequency spectrum is becoming a limited resource. Many such systems must coexist in a given frequency band. In order to minimize interference among these systems, a radar waveform design is used. Without a priori knowledge of the transmission channel and communication waveform, one viable strategy is to use

We present recent results of a new form of microwave and millimeter-wave imaging called active incoherent millimeter-wave (AIM) imaging that combines noise radar and sparse interferometric imaging techniques. Illumination of the scene with spatially and temporally incoherent noise enables the use of a sparse receiving array to capture information in the spatial frequency domain and reconstruct the

The articles in this special section examine noise radar, a name for radars that use essentially random signals either as the transmitted signal or as the modulation.

This article describes the principles of noise radar, emphasizing the importance of its electronic counter–counter measure (electronic protection) and electromagnetic compatibility performance and reviews some noise radar demonstrators trialed by NATO Research Task Groups. We now understand how to build noise radars with performance comparable with, e.g., a low-power marine navigation radar. Furthermore

In this article, we propose a method to detect the solid-state marine radars that use noise waveforms. The proposed technique makes use of the change in kurtosis between the received noise radar waveform and the receiver's internal noise. Original data from a prototype marine noise radar is used to test the proposed method as well as simulations. The preliminary results show that the proposed method

It is well known that noise-like waveforms have the inherent property of suppressing ambiguities due to their nonrepetitive nature, as opposed to the more classical linear frequency modulated (LFM) pulsed waveforms. This aperiodicity also improves the robustness against jammers, making these waveforms harder to detect and classify by an enemy. However, noise waveforms are Doppler sensitive, requiring
