Abstract :
The algorithm of tracking and localizing a single rapid moving sound target, based on double five-elements-cross arrays, is presented in this paper. The four time-delay-difference values of each array can be estimated by the methods of generalized cross-correlation. And then, the azimuth angle can be calculated with the special structure of the array. The distance between the target and the center of each array can be estimated by the four time-delay-difference values in theory, however, the satisfactory estimating precision of the distance need high estimating accuracy of time delay, and this is very difficult. Therefore, the acceptable position parameter of the target can be gained by the multi- angles of multi-arrays. Double five-elements-cross arrays are placed in one area with 500*500 meters in the simulation, and the estimation error of the azimuth angle is less than 0.4 degree, and the coordinate error is less than 10 meters. The results of the simulation show the algorithm is effective and has high performance.
