A method or radar targets position acquisition based on Possibilistic C_means algorithm

Targets position acquisition is a key technique in radar data processing system. The existence of sea clutter result in the coupling of targets in radar video which lead to the distortion of targets position acquisition. A method for radar targets position acquisition based on possibilistic C_means algorithm is used to solve the problem. During marking different targets by the connectivity and combination algorithm, a method based on possibilistic C_means algorithm is presented to segment coupled targets. The result of the experiment showed that this method can use azimuth and range of radar video simultaneously to realize target position acquisition which can overcome the targets splitting caused by conventional method based on one-dimensional acquisition and can segment coupled targets caused by several factors effectively, thus improving the accuracy of targets position acquisition
