Study on detection techniques for laser fuze using pseudorandom code

With the development of semiconductor laser technology, laser proximity fuzes have been widely used in various kinds of guided missiles and routine ammunitions. An approach to pulsed laser fuze based on pseudorandom code is presented in this paper. Based on the principle of laser fuze using pseudorandom code, the system has been divided into emitting module, receiving module, optical system and information processing module. The different modules have been analyzed in details and principles for selecting the parameters of the modules are given. The testing shows that laser fuze based on pseudorandom code has a better ability of detection and a higher resistance to interference. The theoretic foundation is provided for scientifically designing pulsed laser fuze of pseudorandom code.
