Geolocation of Frequency-Hopping Transmitters via Satellite
Abstract
A satellite-communications terminal geolocation is analyzed by satellite interception, whereby a number of spaceborne interceptors transpond the frequency band of interest to a terrestrial location for processing. The general formulas for the interception accuracy are summarized, and a strawman interceptor system is proposed. Interception regions for prototypical terminals and satellites are calculated and the results are presented parametrically as a function of uplink SNR. The optimum angular separation of the interceptor satellites is found, and the effect of nonoptimal separation is discussed. The practical limitations involved in implementing this geolocation system are also discussed. (RRH)
