Abstract

Single photon ranging has high sensitivity and can effectively improve the measurement range. In order to improve the target detection efficiency of commonly, we use the method of multiple accumulation to improve SNR. For moving target echo signal, each has a certain offset. The echo signal accumulation broadening greatly increases the difficulty of signal extraction. The traditional method is using multiple filters. But for single photon signals, the filtering method is not effective. This paper studies the single photon echo ranging model. The mathematical model of the echo signal of moving target is established. Accumulation of moving target with velocity estimation overcomes the accumulation of the problem. Compared with the traditional filtering method, it has more superior performance. And the detection probability of the method is calculated by Matlab simulation, verifying its good performance.
