In order to be more adaptable to the upgrading of airborne equipment and enhance the capability of the fighters, the power management of airborne radar under active interference condition in air-to-air combat is researched from the pilots’ point of view. The effect of radar power management on electronic warfare interception is analyzed firstly. According to the numerical simulation results based on flight training data, the mismatch range of target Electronic Support Measure(ESM), the tracking range of the radar and the interception range by the target ESM compose geometric series. Then the relation between the mismatch range and burn through range is discussed. It is concluded that power manage measures should be taken on condition that the radar is superior to the target ESM obviously, otherwise the measures should not be taken in case of radar losing energy advantages over the target interference.
