摘要：

Ground target measurement is of great significance to improve the ranging accuracy of SLR system, which can obtain the system delay and calibrate the system error. Based on the principle of ground target measurement with SLR, the model of ground target ranging was established by using Monte Carlo method, and the SLR ground target ranging simulation was realized. From the view of noise, the method of adaptive noise correlation matching(ANCM) algorithm was proposed to eliminate the noise in ground target ranging data. The echo noise template was constructed based on the actual measured data of short-term static background noise and the threshold value of random noise, combined with the simulated ranging data generated by SLR ground target measurement model, by optimizing the selection interval of data, the iteration times and other parameters, the effective return signal of ground target was extracted. Compared with traditional ground target data processing algorithm, the effective return points from ground target in Changchun Observatory/National Astronomical Observatories, Chinese Academy of Sciences is increased by more than 30% with ANCM algorithm, the ranging accuracy of data processing is improved by around 2 times, the efficiency of ground target data is significantly improved, it also provides a new idea to obtain the delay value of SLR system accurately. © 2021, Editorial Board of Journal of Infrared and Laser Engineering.
