Offner type polarization spectrum integrated space target observation device and space target observation method

Abstract

The invention provides an Offner type polarization spectrum integrated space target observation device, which comprises a synchronous lens changer, an Offner spectrometer light path module and a polarization imaging light path module; wherein the polarization imaging light path module is used for observing a specific target area, and then the synchronous lens changer dynamically switches the polarization imaging light path module to the Offner spectrometer light path module; the Offner spectrometer optical path module is used for collecting and imaging a spectrum of the specific target area. The Offner type polarization spectrum integrated space target observation device of the invention integrates observation of brightness information, spectrum information and polarization information ofthe space target into one device, and solves the problems of difficult multi-parameter extraction, low extraction efficiency and high recognition error rate in space target detection. The invention also puts forward a space target observation method.

Description

technical field [0001] The invention belongs to the field of space target recognition and spectrum detection, and in particular relates to an Offner type polarization spectrum integrated space target observation device and a space target observation method. Background technique [0002] The main work content of my country's ground-based astronomical telescopes is the observation and early warning of space debris in medium and high orbits. The main content of space target observation technology is the identification and judgment of space targets. Therefore, providing a technology and method for identifying multiple characteristic parameters of medium- and high-orbit space debris is an urgent problem to be solved in the field of space debris observation. A large number of existing scientific research results show that combining brightness information, spectral information and polarization information into one to detect and analyze space debris will bring a significant improve...
