HJ-1-C卫星SAR全功率辐射试验的设计及实现

摘要

该文面向HJ-1-C SAR全功率辐射试验设计，阐述了SAR大功率集中发射所带来的新问题，从保证雷达接收通路的安全性出发，提出全功率辐射试验的接收通道漏过功率测试的必要性，给出构成雷达系统收发通道闭环测试的方法。试验结果表明，所提出的 HJ-1-C SAR 系统全功率辐射试验的方案合理可行，试验达到了预期的效果。%In this paper, the HJ-1-C SAR full-power radiation test design is presented. For the new problems caused by SAR high-power concentrated emissions, the radar-receiving channel-leakage power test is proposed to ensure the safety of the radar-receiving path, and the transceiver channel closed-loop radar system test is discussed. The experimental results show that the proposed HJ-1-C SAR full-power radiation test scheme is reasonable and feasible, with the desired outcome.
