摘要：

The foundation of countering the towed radar active decoy (TRAD) is the presence detection of decoy. Derivation of monopulse radar angle error output of balanced phase discriminator (BPD) with and without towed radar active decoy was demonstrated. According to the principle of BPD, the conclusion can be obtained that the Doppler frequency difference between target and decoy would affect the angle error. There was no variation when the angle error passed through the low pass filter without the decoy jamming; there was a change under the condition of decoy jamming. The alternating part of the angle error was filtered out by the low pass filter. Based on the variation of angle error with and without decoy, threshold detection was used to detect the towed radar active decoy. Simulation analysis under different jamming conditions was performed on the detection performance of the proposed method, and its effectiveness was validated. © 2017, Editorial Board of JBUAA.
