In order to effectively detect moving targets in heavy sea clutter, the micro-Doppler (m-D) effect is studied and an effective algorithm based on short-time fractional Fourier transform (STFRFT) is proposed for target detection and m-D signal extraction. Firstly, the mathematical model of target with micromotion at sea, including translation and rotation movement, is established, which can be approximated...
In order to effectively detect moving target in strong sea clutter, a detection algorithm for moving target based on clutter map cancellation in fractional Fourier transform (FRFT) domain is proposed. Radar data in FRFT domain are noncoherently accumulated with the single pole feedback clutter map (SPFB-CM) in FRFT domain, which are used to suppress sea clutter and improve signal to clutter ratio...
