Abstract

Features of creation of homodyne receiving paths of LFM-CW radar with wide-band signal of 3 cm and millimetric range are considered. It is shown that for increase in dynamic range the homodyne receiver of the radar has to have two frequency conversion. The first converter is carried out on the monolithic IC based on GaAs, and the second using MIC on the Si or SiGe technology. For such scheme the assessment of achievable dynamic range was made, the obtained experimental characteristics of radio paths and radar images received with the radar are provided.

调频-连续波雷达同差接收微波信道动态范围的增大

考虑了LFM-CW雷达在3cm和毫米波段的宽带信号下的同差接收路径的创建特点。研究表明，为了增大动态范围，雷达的同差接收机必须进行两次变频。第一个转换器是在基于GaAs的单片IC上实现的，第二个转换器是在Si或SiGe技术上使用MIC实现的。针对该方案进行了可实现动态范围的评估，给出了得到的无线电路径的实验特性和雷达接收到的雷达图像。
