A Two-Step Sequential Procedure for Improving the Cumulative Probability of Detection in Radars

L. E. Brennan, Francis S. Hill

ResearchPublished 1964

A discussion of a simple two-step search precedure for phased-array radars. The two-step procedure consists of illuminating each beam position in turn with a single transmitted pulse, and testing for the presence of a return signal from a target in each of m range positions. First the Memorandum considers this two-step scheme for five target scintillation models, and the single-scan detection probability (blip/scan ratio) is plotted and compared with the conventional single-pulse detection probability. Second, it extends the two-step detection method to the computation of cumulative detection probabilities. A discussion of a simple two-step search procedure for phased-array radars.
