A second-phase study of radar multiple-stage decision processors which minimize the average transmitter power and data processing costs for performing the surveillance mission are described. Energy Variant Sequential Detector EVSD theory is reviewed. A sequential detection scheme for performing high-resolution surveillance missions where relatively large time- bandwidth products are involved is described. These modes designated as Resolution-Variant EVSDs use the programmed control of the time-bandwidth product of the transmitted signal, the transmitted energy, and the receiver thresholds on the sequential steps employed in order to minimize both the transmitter power and the parallel signal processing costs. General implementation of EVSDs are reviewed. The optimum scan time to be used when EVSDs are employed for each scan look is developed for both the case where the target is pointing directly at the radar, and the second case where the target range is assumed relatively constant for the time duration in the surveillance volume. EVSD modes which include an option on the time interval between sequential steps are described, and the additional power savings over the use of a conventional EVSD are computed.
