Dynamic Multi-Target Detection and Focus in Maritime Conditions

This paper presents an application of Doppler beam sharpening (DBS) to focus and enhance the resolution of multiple ‘dynamic' targets in maritime environment. The current limitations in radar-based maritime sensing have been analysed followed by adaptive DBS approach to detect and focus extended targets using traditional DBS, adaptive thresholding, and density-based clustering. Based on this, targets have been simultaneously focused with lower sidelobes and removal of Doppler sidebands inherent to DBS. Demonstrated experimental results have shown feasibility of proposed technique in improving target detection.
