PCM signal intermittent transmitting and receiving complementary design and echo reconstruction method
Interrupted transmitting and receiving in radiation simulation can effectively solve the problem of mutual coupling between signals,but it will also bring about signal loss,which will result in high sidelobes in range profile of the phase code modulation signal.To solve this problem,an intermittent transceiver complementary sequence design method is proposed and the design of complementary sequences is also given,and recombines the phase code modulation intermittent transceiver echo to eliminate the echo loss caused by intermittent transceiver and obtain accurate target range profile.Simulation results show that the design of complementary sequences and echo reconstruction splicing can accurately reconstruct the echo,and the reconstructed cross-correlation coefficient is close to 1,which verifies the feasibility and correctness of the proposed method.
