摘要
1. A doppler frequency impulse radar system, comprising a transmitting circuit for transmitting an impulse modulated carrier wave and a receiving circuit for receiving reflected echo impulses, said transmitting circuit including means for transmitting a first pulse sequence and means for transmitting a second pulse sequence having identical period durations, means for effecting a time displacement between the transmission of the respective pulse sequences which displacement is so selected that periodically recurring gaps appear in the spectral line spectrum of the transmitted signals, and doppler frequency filters operatively disposed in the signal path of the receiving circuit having a pass range corresponding to at least one of said gaps and having a pass width which is somewhat smaller than the width of a gap.
