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%.
