k-stage signal detection

The k-stage detection procedures, which generalize familiar truncated sequential signal detection procedures, are studied. Various modified versions of the k-stage detectors are introduced. An efficient method for calculating characteristics and optimizing parameters of the k-stage detectors and their simplified versions is described. One-channel and multichannel k-stage detectors of coherent and noncoherent pulse bursts are analyzed, optimized, and compared with familiar Wald's detectors and detectors with a fixed size of the sample sequence.
