摘　　要：灵敏度时间增益控制(STC)模块是雷达接收机免受近程杂波干扰而过载的重要保护部件。针对模块在应用中增益控制精度高的要求,提出了一种将计算机软、硬件技术和仪器自动测量技术相结合产生高精度增益控制数据的方法。设计了增益控制数据可重构的STC模块和辅助软件,将STC模块和运行辅助软件的PC机、矢量网络分析仪、高低温箱组成闭环系统。通过辅助软件自动控制,实现了不同温度下增益控制量的自动采集、选择、插值、重构和自动验证结果等功能,使用此方法的STC模块增益控制精度为±0.5 dB。结果表明,该方法具有自动化程度高及生成曲线误差小等特点,与传统生产方法相比,模块生产效率提高了60%。The STC module is an important protective unit,which make radar receiver avoid overload because of short range clutter interference.In order to meet the requirement of high-precision gain control in application,a method of combining computer software and hardware with instrument automatic measure technology to generate high-precision gain control data is proposed.Firstly,STC module that gain control data can be reconstructed and assisting software are designed.Then,the STC module,personal computer running assisting software,vector network analyzer and high-low temperature chamber forms a closed-loop control system.Finally,the assisting software uses the automatic control way to implement such functions as automatic data collecting,data selecting,data interpolating,data reconstructing,as well as automatic verification of results.The output gain control precision of STC module is±0.5 dB.The results show that the method has such characteristics as high automation,low curve error and so on.The efficiency of module production is improved60%compared with the traditional production method.
