A space-based space target detection device based on photon counting time marking technology

Abstract

The invention discloses a space-based space target detection device based on the photon counting time marking technology. The device comprises a light shield, an optical system, an MCP position sensitive detector and a signal processing module. Target optical signals are subjected to energy convergence through the optical system and then are transmitted to the MCP position sensitive detector. The target optical signals are subjected to photon counting and imaging by the MCP position sensitive detector. Signals outputted by the detector are processed by the signal processing module. In this way, the arrival time and the position coordinate information of the target optical signals are obtained. Based on the photon counting time marking technology, the position and time information of a target can be obtained. Therefore, the device has the functions of positioning reading, high sensitivity and time marking. Moreover, the device solves the problems of a traditional detection device in detecting weak high-speed moving targets in the prior art.

Description

technical field [0001] The invention relates to the technical field of space-based space target detection, in particular to a space target detection device based on photon counting time marking technology. Background technique [0002] Space target detection is an important basis for space utilization and space control, and is an important topic of future space technology. Compared with ground-based detection, space-based detection has obvious advantages in terms of airspace coverage, surveillance timeliness, small-scale target detection cataloging and early warning. Compared with space-based radar systems, space-based optical detection has the advantages of low power consumption and high angle measurement accuracy. With the development of the aerospace industry of various countries, space targets are becoming more and more complex, including tiny satellites and space debris. Therefore, there is an urgent need to develop space-based optical detection technology for space t...

AI Technical Summary

Problems solved by technology

Therefore, the traditional detection system based on CCD or CMOS detectors can only detect targets with slower speed, shorter distance and larger size, and cannot meet the needs of long-distance tiny targets and short-distance high-speed moving targets.

So far, there is no device for detecting weak and high-speed moving targets in space
