摘要： 针对雷达在对抗特定的ESM侦察设备时被截获距离难以直接测试的问题，研究了雷达被ESM侦察设备截获距离的等效试验方法。首先，推导了期望试验条件和替代试验条件下被截获距离的等效模型。然后，针对不同的试验场景，将等效模型细分为四种不同的类型。最后，通过某型雷达被截获距离外场试飞的实测数据对等效模型进行了验证。试验结果表明等效模型的误差为7.26%，满足试验大纲误差小于10%的要求。

The research of radar intercepted distance by equivalent test

Abstract： Aiming at the problem that it is difficult to directly test the intercepted distance between radar and specific ESM reconnaissance equipment, the equivalent test method of radar intercepted distance by ESM reconnaissance equipment is studied. Firstly, the equivalent model of intercepted distance under the expected test condition and the substitute test condition is deduced. Then, according to different test scenarios, the equivalent model is subdivided into four different types. Finally, the equivalent model is verified by the measured data. The data is from the intercepted distance of a certain radar in the outfield flight test. The test results show that the error of the equivalent model is 7.26%, which meets the requirement that the error of the test outline is less than 10%.
