一种基于一致性理论的卫星协同自主探测方法

A Cooperative and Autonomous Detection Method Among Satellites Based on the Consensus Theory

摘要:

为了提高天基空间碎片探测系统对空间碎片探测能力,研究了一种基于一致性理论的卫星协同自主探测方法,对系统中的卫星进行协同控制,从而实现对空间碎片进行最长时间的持续跟踪探测。探测星座利用招投标机制选取探测效果最好的卫星,空间碎片周围的卫星载荷再利用一致性理论,协同自主地指向空间碎片,以实现探测星座对空间碎片连续跟踪。仿真结果说明了该方法的有效性,1d内探测星座对典型空间碎片的最大连续观测时间由协同前的 6 min提高到了协同后的 39 min,提高了约 5倍,总观测时间由协同前的 1.5 h提高到 13 h,提高了约 8倍。该方法提高了观测效能,可为天基空间碎片探测系统提供一种对空间碎片协同探测的技术途径。

Abstract:

In order to improve the detection ability of the space-based space debris detection system, a cooperative and au. tonomous detection method based on the consensus theory was proposed. The satellites of the system were controlled coop. eratively to follow the space debris as long as possible. The satellite which had the best detection effect was selected by the process of bidding. Then the satellites detectors were pointed to the space debris autonomously based on consensus theory. The simulation result indicated the availability of the method. In one day, the maximum continuous observation time to the typical space debris extends from 6 minutes before the cooperation to 39 minutes after the cooperation. It increased about 5 times. The total observation time extended from 1.5 hours to 13 hours. It increased about 13 times. So it improved the ob. servation efficiency observably. This method can offer a technology approach of cooperative detection to the space debris for the space-based space debris detection system.
