Doppler Compensation Algorithm Based on Pseudorandom Sequence
Because binary phase-coded signal is sensitive to Doppler frequency, a new compensation algorithm is introduced in this paper. The returns can be cancelled through the algorithm which takes advantages of the property that neighboring returns have almost equal Doppler frequency. The algorithm is based on pseudorandom sequence (m-sequence) and can well meet the needs of low intercept possibility characteristics. It only focuses on signal processing therefore it is easy to be applied in typical full-wave radar. Theoretically, through the algorithm any number of moving targets and any Doppler frequency can be compensated accurately.
