摘要
为解决X/Ka信道在建设和运行维护过程中测试设备笨重、功能单一、设备操作复杂、工作状态无法获取等弊端,通过优化中频与射频链路方案、小型化与多功能集成设计、集中监控与射频线缆供电等方式,设计了一种便携式X/Ka频段遥感卫星接收信道测试系统,实现了1GHz宽带X/Ka卫星数据地面接收系统射频(7.9~8.9GHz、18~20GHz、25~27.5GHz3个频段,有线或无线)、中频环路的调试和测试(1.2GHz、1.5GHz2个频段)及信道的测试系统的集中监控、高阶调制、多种编码、多普勒仿真、噪声源添加等功能,极大地方便了现场或野外测试应用。
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.
