An Active Sonar Signal Detection Algorithm Based on Weighted Neighbourhood Relative Entropy in the Underwater Acoustic Noise Environment

This paper presents a target detection method for active sonar based on weighted neighbourhood relative entropy (WNRE), using tools from information geometry. The method segments the matched-filter output of each echo by a sliding window, estimates the probability density of every window by kernel density estimation, a...
