DETECTION RESULTS FOR FLUCTUATING TARGETS.
Abstract
Sea-clutter measurements using high-resolution radar indicate that clutter cross-section returns do not usually follow a Rayleigh distribution. The log-normal and contaminated-normal descriptions of sea clutter have been considered; and detection curves for nonfluctuating targets and for these distributions have been generated for the mean, median, and trimmed-mean detectors. In this report the detection calculations are repeated for fluctuating targets, specifically Swerling II and IV fluctuations. For the log-normal distribution, the trimmed-mean is the most effective detector; and the median is slightly better than the mean. For the contaminated-normal distribution, the mean is slightly better than the trimmed-mean, which is better than the median. (Author)
