Non-coherent integration losses of wideband target detection

Abstract

The use of wideband radar signals is sometimes more preferable for solving not only the tasks of target resolution, recognition, measurement, and the illumination stealth, hut the traditional task of detection too. The latter is due to the decreased fluctuations of echoes. However, if the signal has an excessively wide bandwidth, the losses of noncoherent integration increase and the threshold signals rise. We investigate the detection threshold signals for the targets of different sues, for illumination signals of various bandwidths, and for detection of different type.
