Abstract: Aiming at the need of air defense interception, the location principle of the least square method between the missile and the ground static station is analyzed based on the basic theory of the time difference and direction finding method. By comparing multiple location methods of missile and ground station co-location, a kind of technology is proposed to improve the tracking accuracy of the interference sources. A set of simulations are implemented to compare the accuracies of different location algorithms.

Key words: self-defense jamming, missile-borne combined with ground station, time difference direction-finding method, target position, least square(LS), geometric dilution of precision(GDOP)
