Abstract

Radar surveillance of unmanned aerial vehicles (UAVs) is actively developing area of scientific research. This article provides a review and analysis of publications in recent years devoted to the methods and radar systems of detection and recognition of classes and types of UAVs. It is noted that the most difficult targets for radar detection are low-sized, low-speed small UAVs (drones) flying at low and extremely low altitudes. If large and medium-sized UAVs can be detected by modern radar systems, then for the detection of small UAVs it is advisable to create specialized highly efficient, highly mobile, portable and inexpensive active UAV detection radars. The technical requirements for such radars are defined and recommendations for their implementation are provided. High-performance protection systems based on adaptive lattice filters are offered to protect UAV detection radars from noise jamming and passive interference. It is shown that the research on the methods of recognizing UAV classes and types is a development of the existing theory and technology of radar recognition of air targets.

无人机的雷达监视（综述）

摘要

无人机的雷达监视正在积极地发展科学研究领域。本文提供了对近年来出版物的回顾和分析，这些出版物专门介绍了检测和识别无人机类型和类型的方法和雷达系统。值得注意的是，雷达检测最困难的目标是在低空和极低空飞行的小型，低速小型无人机（无人机）。如果现代雷达系统可以探测到大中型无人机，那么对于探测小型无人机，建议创建专门的高效，高度移动，便携式和廉价的有源无人机探测雷达。定义了此类雷达的技术要求，并提供了实施建议。提供基于自适应晶格滤波器的高性能保护系统，以保护无人机检测雷达免受噪声干扰和无源干扰。研究表明，对无人机类别和类型的识别方法的研究是对现有空中目标雷达识别理论和技术的发展。
