The range difference between the target and the towed radar active decoy (TRAD) supplies the opportunity to distinguish them in distance for the radar seeker. Based on detailed analysis about this range difference, the Step Frequency-Pulse Doppler (SF-PD) waveform was adopted to replace the conditional quasi-continuous waveform, and appropriate parameters were designed to supply a relative strong Doppler resolution as well as some range resolution. With the advantage of this new waveform, the discrimination of the target and decoy is achieved and simulation results illustrate the effectiveness of the proposed method.
