Abstract: Data association algorithm is one of the key technologies about radar data process. Nearest neighbor algorithm and the probabilistic data association algorithm use target position as traditional data association method. When Target in the echo and cluttered environment,the capability of the traditional data association method based on the position get worst,and cause to target lost. In this paper,according to the DS evidence theory,introduce a new data association method base on the target multiple feasure. For the steady target,using position state,signal amplitude, azimuth change feasure when measurement-track data association,to speculate the possibility that the dot is from the real target. The results demonstrate that the multiple features joint data association algorithm has the value of application and improves the tracking performance in clutter area and closely spaced targets area by validating with the real radar data.
