Paper Abstract

A numerical method is proposed to estimate the cumulative probability of detection for a surveillance radar that attempts to detect a target closing in range, within a fixed range window, with a desired level of confidence. In this case, one or more radar scan-target intersections may occur anywhere within the range window depending upon the timing of the radar scan, the timing of the target entry into the window, and the locus of the radar-to-target range along the trajectory. This detection scenario could, for example, arise as a result of a sophisticated search strategy adopted by a surveillance radar utilizing an electrically scanned array to achieve a higher degree of efficiency in radar resource management. Single-scan probabilities of detection within the range window can be measured by observing radar performance during repeated test against a suitable target trajectory. These measurements can then be used within a Monte Carlo-style computer simulation of multiple target trajectories to construct a probability density function from which an estimate of cumulative probability of detection and confidence limits can be derived. This approach enables performance verification results to be used for predicting performance under alternative target trajectory scenarios.
