Space target detecting and tracking system utilizing starlight occlusion

机译:利用星光遮挡的空间目标探测与跟踪系统

摘要

A system for detecting and tracking targets or objects located in the earth's shadow. The system senses and processes starlight from one or more stars. More particularly, the stellar background provides an illumination source with which targets are detected as they eclipse or occlude one or more stars. The system includes a receiver which collects incident starlight and a sensor, coupled to the receiver, for sensing the collected starlight focused thereon by the receiver and for providing a sensor output signal indicating the intensity of the sensed starlight. A signal processor, responsive to the sensor output signal, provides a target detection signal indicating whether a target has crossed the line of sight between the receiver and one or more stars. The signal processor may be further responsive to a stellar background catalog for providing the target detection signal with bearing information indicating the bearing of a detected target.
