Measurement Fusion Method against False-Target Jamming for Radar Network

In the presence of multi-false-target deception jamming, a single station radar has no perfect performance in anti-jamming with its angle of view single and the limitation of the number of measured dots. For this problem, a true or false target recognition method is proposed for concentrative radar network in this paper, which fuses the measurements by spatial-correlation processing technique based on the location and velocity of the measurements. For the association sequence of measurements, measurements fusion based on location is used first. Then, the velocity vector is calculated and applied to fusion, so as to eliminate false-target from the result of fusion based on location. The deceived probability of radar network is made lower without the decrease of recognition probability of the true target.
