Abstract:
A network device determines an exposure time associated with an image sensor coupled to a spacecraft for capturing an image of a target object orbiting the Earth. The network device computes a maximum relative angular velocity associated with the target object based on the exposure time and a dimension of a pixel of the image sensor. The network device identifies a first pointing direction of the image sensor for initiating a search for the target object. The network device generates a first angular velocity probability distribution map for the target object and divides the first angular velocity probability distribution map into a first set of angular velocity regions (AVRs). The network device selects a first AVR from the first set of AVRs for scanning by the image sensor and generates a search schedule that includes a first entry for informing the spacecraft to scan the first AVR.
