Clustering Method Using a Monopulse for Divided Detection of Closely Spaced Airborne Targets

Abstract

In a radar system, a clustering algorithm is mainly used to group adjacent cells using CFAR algorithm results. However, in closely spaced airborne targets, it is difficult to divide the targets using common clustering methods. Therefore, this paper proposes a clustering method using a monopulse rather than increasing the range and Doppler resolution. Even with adjacent hits, if the monopulse value is more than a specified threshold, the results are not grouped into one cluster.
