As an important component of a modem radar system, Automatic Target-Position Acquisition (ATPA) sub-system is responsible for estimating radar targets' center positions. Among all the ATPA algorithms, old-fashioned Binary-Processing (BP) algorithm is in an almost-obsolete state. Today the most widely used algorithm is Area-Center (AC) algorithm. But Centroid algorithm has gained more and more attention because it has better precision and requires simpler data structures. However, all the above algorithms are unable to completely solve the problem of signal expansion in range dimension, which is caused by pulse-compression technique. For long-range surveillance radar systems, if this problem remains unresolved, it is impossible to achieve high resolution of azimuth and range. Thus in this paper, we propose a 2-Dimensional Centroid algorithm based on the original Centroid algorithm, which is only 1-Dimensional. In addition, we also designed a simplified peak-searching (P S) algorithm according to the characteristics of long-range surveillance radar. Analysis and simulation shows that this algorithm has relatively high estimation precision, and its implementation scheme is very easy. It has already been successfully used in some kind of long-range surveillance radar system.

In the paper a new algorithm to find peaks in two, three and multidimensional spectra, measured in large multidetector gamma-ray arrays, is derived. Given the dimension in. the algorithm is selective to in-fold coincidence peaks. It is insensitive to intersections of lower-fold coincidences, hereinafter called ridges.
