系统可工作于两种模式：恒星目标检测定位模式和运动空间目标检测跟踪模式。

This system can work in two modes: fixed star detection mode and moving space target tracking mode.

因此，目标反射信号的检测和提取是个难点，也是无源探测定位的关键技术之一。

So, the detection and extraction of signals reflected by the target are difficulties and the key technology of passive tracking location.
