雷达接收机综合测试系统包括真实仪器和虚拟仪器。通过仪表总线、数据采集系统和数字信号处理软件，实现了对雷达接收机参数测试的自动化。文中介绍了雷达接收机综合测试系统的各种测试方法和信号处理算法，内容包括：对数通道特性，动态范围特性，幅频特性，幅相一致性，噪声系数等。该系统已用于多种型号雷达系统的调试，大大缩短了雷达系统的调试周期，改进了雷达接收机的测试方法。

The Radar Receiver Integrated Measuring System(RIMS) includes real instrument and virtual instrument. The RIMS has realized the auto-test to the parameter of radar receiver by GPIB, the data acquisition system and the software of digital signal processing. The method of testing and algorithm of signal processing has been introduced in this paper. The system has been applied to debug various radar systems, and the application shows that RIMS have shortened cycle of testing radar greatly and have improved the process of debuging the radar receiver.
