Doppler Compensation Method Based on m-sequence Signal

For binary phase-coded signal sensitive to Doppler frequence,a new compensation algorithm is introduced in this paper. The returns can be cancelled through the algorithm which utilizes the characteristics that neighbouring returns have approximately equal Doppler frequency.The algorithm is based on pseudorandom sequence(m-sequence) and suitable for the requirement of low intercept possibility characteristics.It only focuses on signal processing,so is easily implemented in typical all-waveform radar.Theoretically,an arbitrary number of moving targets and arbitrary Doppler frequency can be compensated accurately in the algorithm.
