Sequential detection in radar with multiple resolution elements

In this paper the techniques of sequential analysis are applied to a multiple-resolution-element search radar for different types of detection. By using sequential methods such a radar shows considerable saving compared to fixed-scan-rate detection radars. Many of the problems occurring in sequential radar detection are examined; the difficulties of obtaining analytical results for multiple-resolution-element sequential radars are discussed. Most of the results of this paper were obtained by simulation. Included are interesting results which suggest that truncation is not necessary for the tests which were considered. Curves are given describing the improvement obtained by sequential detection procedures. The curves are discussed in detail to make this paper useful to those whose primary interest is in the results which are obtained.
