Performance analysis of sequential detection in early warning radar applications
Hui Zhang, Lingjiang Kong, Xiaobo Yang · 2010
In early-warning radar surveillance environment, sequential procedures are preferred to detect the targets, for they promise a reduction in the time needed to take a decision. In this paper, a sequential detection algorithm is concerned and the interplay between the parameter dsnr and the system performance is mainly discussed. Numerical results have shown that sequential detector can lead a great reduction in the average-sample-number (ASN) especially in high SNR. In order to get a proper system performance, a trade off should be made between the ASN and detection performance when choosing the parameter dsnr.
