Abstract：The precise passive locating and tracking technology for a single observer demands high accuracy estimation of Doppler frequency rate produced by the radial acceleration between the target and the observer from the received signals. The frequency rate cannot denote the Doppler frequency rate for the PSK signal. A phase compensation based algorithm for Doppler frequency rate estimation from BPSK coherent pulse train is presented to conquer the problem. Both the fixed and alterable pulse repetition frequency (PRF) cases are considered. The limitation between the Doppler frequency rate and the sampling frequency, the observing time and the PRF is given. The simulation results show that the proposed algorithm achieves a 4~6 dB lower SNR threshold than the known ones in the typical condition.
