Zusammenfassung:A dual-probe structure is designed, and a differential compensation algorithm is proposed. It can effectively suppress the noise of Photon Doppler Velocimetry(PDV). Through the differential compensation algorithm, the test data is iteratively related to the signal, and the correction of the test speed inversion is realized. The experimental targets with different speeds are tested. From the position change curve, it is known that the position accuracy is higher after the differential compensation algorithm is used, and the speed test fluctuation is increased from 10.25% to 2.43% compared with the non-compensation method. Using this algorithm can effectively improve the signal noise suppression capability
