摘要：
In view of the high false detection rate of traditional secondary filtering algorithm in real-time recognition of weak signal from space debris laser ranging, based on the characteristics of the time correlation of echo signal from space debris laser ranging, a method combining primary filtering and linear fitting is proposed, by which the search cost and recognition accuracy of real-time identification of weak signal is considered and the real-time identification of weak signal from space debris laser ranging is realized. The algorithm was verified using the actual data of space debris laser ranging, and the results showed that the weak signal of space debris can be quickly and accurately extracted by the real-time recognition algorithm for weak signal of laser ranging proposed in this paper, and the false detection rate was decreased from 5.72% to 0.12%, the rate of missed inspection was decreased from 0.77% to 0.34%, which is of great significance to improve the success rate of space debris detection. © 2022, Surveying and Mapping Press.
