Abstract
A time-based computer simulation of space-based radar (SBR) systems is described. This simulator models the orbital dynamics of multiple radar satellites and the characteristics of the radar, and computes the clutter returns from the surface of the Earth as a function of Doppler velocity. It then determines the theoretical detectability of a target of specified radar cross-section, location and velocity at any given time. The simulator has been used to carry out studies of the detection performance of a generic SBR system in a low-altitude polar orbit using near-earth targets in the presence of earth clutter. The results from these studies show that (1) the detection performance varies according to look-direction, and (2) the detection probabilities, in general, decrease with decreasing target latitude.
