Abstract:
1. A method for tracking a plurality of targets, comprising: transmitting a Doppler radar signal from a geosynchronously orbiting satellite, wherein said geosynchronously orbiting satellite has an electronically phase steered antenna for transmitting said Doppler radar signal; creating a plurality of reflected Doppler radar signals by illuminating said plurality of targets with said Doppler radar signal; bi-statically receiving said plurality of reflected Doppler radar signals reflected by said plurality of targets, wherein said plurality of reflected Doppler radar signals are received by a receiving platform; processing within said receiving platform said plurality of reflected Doppler radar signals, wherein a processing output from said receiving platform is a tracking data set representing a present and a predicted location for each of said targets; computing within said receiving platform a fire control solution responsive to an update of said tracking data set for each of said targets; communicating a result of said fire control solution to said geosynchronously orbiting satellite; modifying a pointing angle of said electronically phase steered antenna to maintain a continuous surveillance of said plurality of targets; and updating said fire control solution by repeatedly communicating an updated result of said fire control solution from said receiving platform to said geosynchronously orbiting satellite and repeatedly modifying said pointing angle of said electronically phase steered antenna in response to said updated result of said fire control solution.
