摘　　要：介绍了一种采用等效法检测二次雷达作用距离的解决方案。方案中在应答机端口设计程控衰减器,能够在二次雷达询问机和应答机之间相距不同距离时采用等效法都能实现作用距离检测。此外在衰减器上加入温度传感器,能够实时得到程控衰减器的环境温度。根据当前温度确定衰减器的实际衰减值,可进一步提高检测结果的准确性。It mainly introduced the solution which adopts method of equal effects to detect the operation range of SSR.In the solution,the pro- grammable attenuator was designed in the transponder.It can implement detection of SSR operaion range when the distance between SSR interrogator and transponder is different.Besides temperature sensor was designed with the attenuator, this can batain the current temperature in real time,and the ac- tual attenuation value can be confirmed according to the current temperature ,so as to improve the accuracy of the detection result.
