摘要
Compared with Linear frequency modulated signal, binary phase-coded signal is less applied in pulse radar because of its sensitivity to targets' Doppler frequency shift which could severely destroy the correlation of binary phase code. To resolve this problem, a new compensation algorithm is proposed in this paper. The proposed algorithm is based on m-sequence and can well fulfill the requirements of low intercept possibility characteristics. The outstanding performance of the algorithm is demonstrated by simulation results and the algorithm's realization structures as well as noise's influence on Doppler frequency compensation are also analyzed in the paper.
