  • The laser fuze has advantages of strong anti-electromagnetic interference, high fixed angle and ranging precision, and small size. However, laser fuze's application isn't wide in air defense missiles because of the high false alarm rate. By analyzing the levels of signal feature extraction methods, the contributions of laser echo signal's features to anti-jamming performance and coordinated efficiency of fuze and warhead were discussed, including its energy, delay, pulse width, and information fusion. Then, based on an air defense missile's panoramic laser fuze, the target recognition algorithm was designed using linear array detector. The reliability of target detection is improved obviously, while the visibility of smoke coming down to 110 m, the laser fuze can still detect target exactly.

Abstract: The laser fuze has advantages of strong anti-electromagnetic interference, high fixed angle and ranging precision, and small size. However, laser fuze's application isn't wide in air defense missiles because of the high false alarm rate. By analyzing the levels of signal feature extraction methods, the contributions of laser echo signal's features to anti-jamming performance and coordinated efficiency of fuze and warhead were discussed, including its energy, delay, pulse width, and information fusion. Then, based on an air defense missile's panoramic laser fuze, the target recognition algorithm was designed using linear array detector. The reliability of target detection is improved obviously, while the visibility of smoke coming down to 110 m, the laser fuze can still detect target exactly.
