Abstract:
1. A bistatic radar system for tracking a target comprising: first transmitting means for directing a transmitted Ka band radar tracking signal emanating from a transmitting satellite platform in a geosynchronous orbit around the earth, wherein said transmitted Ka band radar tracking signal is reflected by said target and converted to a reflected radar tracking signal; first receiving means for receiving said reflected radar tracking signal wherein said first receiving means is matched to said first transmitting means and is located on a receiver platform; second receiving means collocated with said first receiving means; second transmitting means for transmitting a tracking reference signal from said transmitting satellite platform wherein said tracking reference signal is received by said second receiving means; processing means located on said receiver platform wherein said processing means outputs a coordination signal containing a correlation of said reflected radar tracking signal with said tracking reference signal to update a fire control solution corresponding to a motion of said target; and a third transmitting means collocated with said first receiving means and said second receiving means wherein said third transmitting means transmits said coordination signal to said transmitting satellite platform to redirect said first transmitting means to update said fire control solution for said target.
