本文介绍了匹配滤波器的概念及利用延时线系统构成匹配滤波器的原理,并说明了利用具有反馈电路的延时线系统实现在雷达接收机检波器以前对雷达回波信号近似匹配滤波器的原理,实现方法,以及与理想匹配滤波器的比较。实现这种系统的雷达在抗人为干扰、抗固定目标干扰、测速、增加作用距离等方面具有独特的优点。
This paper introduces the concept of matched filter and the principle of forming a matched filter by using the delay line system. It also shows that using the delay line system with feedback circuit to achieve the approximate matching of the radar echo signal before the radar receiver detector The principle, the realization method, and the comparison with the ideal matched filter. Radar to achieve this system has unique advantages in anti-human interference, anti-fixed target interference, speed, increase the role of distance and so on.
