摘要
以天基空间目标探测研究为背景,提出了一种空间近距离非合作目标的光学主被动复合探测系统。该系统由扫描和凝视两套被动成像子系统和一套主动激光雷达子系统组成。两套成像子系统的配合能实现大范围搜索,高精度定向及目标的识别、跟踪,克服了以往空间探测器在设计中存在的大视场与高分辨率的矛盾。激光雷达子系统具有对目标精确测距、测速的能力,再配合被动成像子系统给出的目标方位信息,使整套系统可对空间目标进行球坐标定位,计算其轨道参数。在假定条件下进行了系统设计举例,分析了设计中的各个关键技术,给出了系统相应的关键设计参数。为星载光学探测系统设计提供了一种新思路、新途径。
Based on the research of space-based spatial object detectors,a means of active/passive hybrid detection of short-distance spacial noncooperative targets is put forward.The hybrid detection system consist of a scanning imaging subsystem,a staring imaging subsystem and a laser radar subsystem.The two passive imaging subsystems are used to implement large-area searching,high-precision orientation and target identification/tracking.Therefore,the tradeoff between large FOV and high resolution existing in conventional space probe design is overcome.Laser radar has the feasibility of precise measurement of speed and range.Thus with information of target orientation obtained by the passive imaging subsystem,the active/passive hybrid detection system can localize targets in space and calculate its orbit parameters.Under some given conditions,a system is designed as an example,the key technologies are analyzed while corresponding parameters are presented.
