Space debris angle measurement data simulation method

Abstract

The invention relates to a space debris angle measurement data simulation method. The method comprises the steps of dynamically receiving and loading observation plan data of observation equipment by loading polar shift data, dynamically loaded observation equipment information data and dynamically inputting system errors and random errors of the equipment, according to information such as the spatial debris position and speed in a J2000 inertial coordinate system received in real time, converting into a space debris station center position under the J2000 inertial system to obtain a horizontal right ascension and a horizontal declination of the space debris under the J2000 inertial system and a right ascension and a declination of the space debris under a station center equator coordinate system, further converting into an azimuth and a pitch under a horizon coordinate, and adding a system error, a random error and a wild value to generate space debris angle measurement simulation data. According to the method, by loading the observation plan data, the space debris can be observed in a planned manner, the consistency of the simulation environment and the real observation environment is ensured in the simulation process, and the simulation efficiency of the angle measurement data is improved.

Description

technical field [0001] The present application relates to the technical field of space debris detection, in particular to a method for simulating space debris angle measurement data. Background technique [0002] In many fields such as scientific research and military affairs, it is necessary to monitor space debris, determine the position and change of space debris in space at each observation moment, determine the orbit of space debris, and obtain accurate information on space debris. Based on this requirement, accurate measurement of space debris is a very important basic link. Without accurate measurement of space debris, space debris orbit identification, cataloging orbit determination, and precise orbit determination cannot be realized. [0003] Currently, there are mainly two ways to accurately measure the position of passive space debris: angle measurement and distance measurement. However, there are two methods of space debris angulation measurement: absolute posit...
