A Neural Network Approach to the Recognition of the K Distribution Shape Parameter associated with Sea Clutter

Abstract

The main problem faced today by sea radars is the elimination of clutter, which is undesirable contribution that appears mixed with the target information. The unwanted signal is produced by the echo caused by the rebound of the primary emission at the sea surface. One of the most popular probability distributions in clutter modeling is the K distribution. Helpful in efficient detectors design, a system able to recognize the shape parameter of the K distribution, knowing a priori the value of the scale parameter, is proposed. The result is appropriate for real time operating conditions as it’s based on a neural networks approximation in the pattern recognition role.
