Abstract
In construction and operation of X/ Ka-band remote sensing satellite data receiving channels test system,the equipment is heavy,its function is unitary,its operation is complex and its working state can not be obtained. To solve above problems,a new X/Ka-band portable test system is designed by optimizing the intermediate frequency( IF) and radio link methods,miniaturization and multi-function integrated design, centralized monitoring and radio frequency( RF) cable power supply. The system can emit X/Ka-band RF (7. 9~8. 9 GHz,18~20 GHz and 25~27. 5 GHz,wired or wireless) and IF (1. 2 GHz and 1. 5 GHz) signals with 1 GHz bandwidth for the test of satellite data ground receiving system. The system is character-ized as centralized monitoring,variable coding and modulation,Doppler simulation and noise source adding functions. It is very suitable for the site and outdoor test applications.关键词
