一种雷达接收机的优化设计与实现

本文介绍了接收机优化设计的具体思路。其主要功能是将回波信号经两次下变频处理，得到中频信号，然后将中频信号进行放大滤波处理，在进行 AGC 控制后得到功率稳定的中频信号，最终由信号处理组合进行 AD 变换、数字滤波等处理。将传统的微波接收机与中频接收机优化整合，实现接收通道功能模块化，提高了其可靠性和维修性。

Optimal Design and Implementation of Radar Receiver

This paper introduces the concrete idea of receiver optimization design. Its main function is to convert the echo signal by the two down-conversion process, get the intermediate frequency signal, and then the intermediate frequency signal amplifying and filtering processing, signal power stability in AGC control, and ultimately by the signal processing combination of AD transform and digital filter processing. The traditional microwave receiver and intermediate frequency receiver are optimized and integrated, and the function of the receiving channel is modularized, and the reliability and maintainability are improved.
