Survey of Development of Signal Processing Technology for Ship Target Recognition

Abstract Ship target recognition system is the key technology and it is the nerve centre of modern intelligent underwater weapons. The development and achievement of underwater target recognition from more than 20 years ago is introduced comprehensively in order to under- stand the fundamental principle and function of the targets recognition technology. The modern signal processing technologies such as spec- trum analysis, wavelet analysis and chaotic time series which are applied in underwater target recognition are proposed especially. The devel- opment trend and thinking of the future for the target recognition is proposed finally, it is expected that the subject of the ship target recogni- tion and feature extraction will get more improvement and development with our endeavor.
