Abstract: Aimed at the complexity in the actual operation of the laser fuze, a new simulation software was designed for target detection and recognition of laser fuze. Taking laser proximity fuze as application background, a laser missile model with the six quadrant laser launch system was developed. Through calculated echo power by target reflection method for different target, the system could complete target detection and identification, launch missiles according to the echo power threshold judgment, and finally complete the whole process of fuze dynamic simulation. The function test results of the laser fuze simulation software show that the developed module is reasonable, the operation is normal and it meets the use requirement.
