Abstract

The invention discloses a space target detection method and device under complex star background. The method comprises the following steps that measuring requirements are obtained, wherein the measuring requirements comprise the measuring range, field angle and target speed; cooperative target parameters are obtained, wherein the cooperative target parameters comprise optical power and the workingangle; working data of a star sensor are obtained, wherein the working data comprise frequency and sensitive wavelength; and an inter-satellite measuring model is established and a relative angle measuring algorithm is designed to obtain space target detection results. By applying the performance advantages of the star sensor to space target detection, the advantages of high precision and high update rate of the star sensor can be effectively utilized in the field of space detection, and ideas and engineering practice are provided for the development and application of star sensors.

Description

technical field [0001] The invention relates to the technical field of space target detection, in particular to a space target detection method and device under a complex starry sky background. Background technique [0002] Inter-satellite relative measurement technology is the basis of precise satellite formation. At present, satellite formation missions have high requirements for relative position measurement accuracy, which has reached centimeter or even millimeter level. Measurement methods currently include GPS (Global Positioning System), microwave radar, laser radar, and vision. The measurement accuracy of the relative position of the GPS carrier is relatively high, and the static relative positioning accuracy of the ground point can reach 10-7~10-8m; the error of the microwave radar is divided into a systematic error and a random error that can be calibrated and solved, and the baseline distance of 5~7km In general, the distance measurement accuracy can be better th...
