The Methods of Laser Guided Signal Information Identification

摘要

The aim of laser guided weapons adopting laser code and decode is to resolve the mutual interference of multiple irradiator in the same war zone. As an effective interfering means, active interference makes the laser guided weapons lose the right object information to protect the important objects in the attack phase by sending much interfering signal. But how to intercept, capture, analyze and identify the laser guided signal code information real-time is the first task in the laser countwork. Based on analyzing the characters of existed laser coding and wave gate, combining the time-correlation character of laser guided signal, this paper proposes the technique of laser guided signal information autocorrelation identification, and it is studied deeply by simulation and experiment. The result shows that the technique resolved the difficult problem of copying the enemy laser signal in short time effectively. The technique wins the time for the laser countwork, and it is feasible and takes on military application value.
