Algorithm of automatic target-position acquisition for long-range surveillance radar
Peng Yingning · Journal of Tsinghua University(Science and Technology) · 2002
Range extension caused by pulse compression is not well resolved in most automatic target position acquisition (ATPA) algorithms. This paper presents a two dimensional centroid algorithm, which is an extension of a one dimensional centroid algorithm. A simplified Peak Searching (PS) algorithm is also presented based on the characteristics of long range surveillance radar. Simulations show that this algorithm has higher estimation precision than the traditional area center (AC) algorithm. The algorithm is also easily implemented because of its recursive structure and low memory. The algorithm has already been successfully applied to a long range surveillance radar system.
