Purpose

The purpose of this paper is to outline a novel concept of radio altimeter CRW-13 that has been designed and developed in the Lukasiewicz Research Network – Institute of Aviation as a result of the need to update the outdated structure of RWL-750M.

Design/methodology/approach

The new design of the device consists of integral antennas and signal processor for smart digital signal filtering.

Findings

As a result of a number of laboratory tests and flight tests of the device installed on MP-02 “Czajka” ultralight aircraft promising results were achieved. They allow to move on to the next stage of implementation and preparation for the device certification.

Practical implications

The CRW-13 meets with great interest of civilian and military potential customers. It is an ideal solution for airplanes, helicopters, unmanned and guided missiles. The universal design enables installation on many different platforms where exact height measurement is needed and crucial.

Originality/value

At the origin of the new concept was the need to replace the separate transmitting and receiving antennas with one unit comprising two planar microstrip antennas placed directly next to each other on a common plate block in the transceiver. This solution eliminates thick antenna cables and coaxial connectors, which are the most unreliable and problematic elements of radio altimeters. The new concept of integral antennas and the use of signal processors for smart digital signal filtration made it possible to take the technology to the next level.

CRW 13 –新一代无线电高度仪：概念，设计和测试

目的

本文的目的是概述由于需要更新RWL-750M过时的结构而在Lukasiewicz研究网络–航空学院中设计和开发的无线电高度计CRW-13的新概念。

设计/方法/方法

该设备的新设计包括集成天线和用于智能数字信号滤波的信号处理器。

发现

通过对MP-02“ Czajka”超轻型飞机上安装的设备进行的多项实验室测试和飞行测试的结果，取得了可喜的成果。他们允许进入下一阶段的实施和准备设备认证。

实际影响

CRW-13引起了民用和军事潜在客户的极大兴趣。它是飞机，直升机，无人驾驶和制导导弹的理想解决方案。通用设计可将其安装在需要精确测量高度且至关重要的许多不同平台上。

创意/价值

新概念的起源是需要用包含两个平面微带天线的单元来代替单独的发射和接收天线，两个平面微带天线彼此直接相邻放置在收发器的一个公共板上。该解决方案消除了粗线天线电缆和同轴连接器，它们是无线电高度仪中最不可靠且最成问题的元件。集成天线的新概念以及对智能数字信号滤波的信号处理器的使用使将技术提升到一个新的水平成为可能。
