Abstract

The ongoing increasing demand for electromagnetic spectrum due to a strongly developing market for communication systems makes it difficult to perform safe operation of modern radar systems as there are more and more emitters operating at nearby frequencies. Also the operation of several radar systems of the same kind may rise interference problems in cases where the available bandwidth is limited and leading to overlapping in frequency regions. Interferences caused by those circumstances can cause significant performance losses of the radar systems. By means of a new radar concept, which is known under the title “Cognitive Radar” [1], [2] new solutions for this problem can be found. This paper discusses the architecture of how the “Cognitive Radar” can be constructed, i.e. which components are necessary in the architecture and how they have to interact with each other to characterize a “Cognitive Radar” approach. As an example, a method using adaptive processing for suppression of strong interference signals is presented. Finally, a quick overview of applications in upcoming radar systems, which achieve a significant market advantage with the help of this new technology, will be presented.

认知雷达原理及其在干扰抑制中的应用

由于通信系统市场的强劲发展，对电磁频谱的需求不断增加，使得现代雷达系统的安全运行变得困难，因为越来越多的发射器在附近频率工作。此外，在可用带宽有限的情况下，同一类型的多个雷达系统的操作可能会产生干扰问题，并导致频率区域重叠。由这些情况引起的干扰可能导致雷达系统的重大性能损失。通过一种新的雷达概念，即“认知雷达”[1][2]，可以找到这个问题的新解决方案。本文讨论了如何构建“认知雷达”的体系结构，即哪些组件在体系结构中是必需的，以及它们如何相互交互以表征“认知雷达”方法。作为实例，提出了一种利用自适应处理抑制强干扰信号的方法。最后，将快速概述在即将到来的雷达系统中的应用，这些系统在这项新技术的帮助下取得了显着的市场优势。
