Empirical models for detection prediction in K-distribution radar sea clutter

Simple empirical models are described which enable the radar designer to determine single-scan detection probabilities from the signal-to-clutter ratio and false alarm probability, for the compound K-distribution clutter model. The method to apply these results is discussed in detail, and the variability of the clutter rejection coefficient is briefly reviewed. Results covering the following are presented: the average clutter reflectivity, the shape parameter for the K-distributed clutter amplitude distribution, detection performance for targets in clutter, and evaluation of performance in clutter and noise
