摘要
给出了自行研制的回波模拟器实验样机的原理、性能及其对雷达高度计的测试和定标方法,应用该样机对神舟4号飞船的雷达高度计进行了全系统的地面测试和定标实验。实验结果:有效验证了回波模拟器对雷达高度计的测试和定标方法的可行性,有效验证了神舟4号雷达高度计发射前的动态工作性能。
The principles and performance of an experimental Return Signal Simulator(RSS) with its means of testing and calibration for radar altimeter were given. By using the RSS, the full system ground-based test and calibration experiments were performed for the 'Shenzhou IV' spacecraft altimeter. The results show that the feasibility of the RSS means for radar altimeter test and calibration, and the prelaunch dynamic performance of the 'Shenzhou IV' spacecraft radar altimeter are validated effectively.
