Abstract: The research on the target detection in heavy clutter is very hot in many countries,but the traditional radar target detection technology has shortage,can’t satisfy the complicated war,with the innovative technology of artificial intelligence on,because of the advantages of artificial intelligence in target recognition and feature extraction,the target detection in heavy clutter is practicable,the article accomplished the nonlinear prediction of sea clutter,by fitting the nonlinear dynamic of sea clutter based on the artificial intelligence technology,and provided a method of Pulse Doppler radar seeker small target detection in heavy sea clutter based on the neural network technology,and the ability of target detection in heavy sea clutter is developed by 2 dB to 6 dB.

Key words: Sea clutter, Artificial intelligence, Neural network, Radar seeker, Target detection
