Range eclipse is a serious problem in high pulse repetition frequency (PRF) pulse doppler (PD) terminal guidance radar. In this paper, we propose a new scheme, which exploits multi-group of dual-frequency pulse waveform, for anti-range eclipse. Each group contains two pulse waveforms with different PRF, which has its own range region of anti-range eclipse and anti-range ambiguity simultaneously. In the scheme, only one pulse group works at a moment, which can avoid range eclipse and effectively measure target distance. According to the changing of target distance, radar switches the pulse group to other group to guarantee target in the range region of no eclipse in the tracking term. Simulation results show that this method can effectively prevent high PRF PD radar seeker from range eclipse.
