  • The Multi-frequency complementary phase-coded (MCPC) signal has caught much attention of researchers recently as a new type radar signal. The narrow band characteristic implied in its synthesized wide band enables it to be more suitable for Moving target detection (MTD) than traditional wideband signals. It is significant to research the MTD of MCPC for realization of multi-function wideband radar. Based on separation of sub-carriers from multi-frequency structure, this paper provides integration method of MTD for such radar signal. After analyzing the gain of Signal-to-noise ratio (SNR) after Doppler processing, the detection threshold and two improved measurements are presented. Processing the MCPC signal as one chip overcomes sampling shift caused by range walk and enables phase-coherent integration. And integrating the peek of Doppler spectrum along velocity lines promotes the effect of integration. The simulation results show that this method can detect the fastmoving target efficiently and guarantee detection performance against low SNR.
