Abstract
In order to study the interference mechanism of high-frequency laser to laser guided weapons, according to the principle of high-frequency laser interference,a series of related theoretical models such as semi-active laser seeker coded identification model, time door model, multi-signal processing model and interference signal modulation processing model were established. Then the 3σ criterion was proposed for interfering the seeker effectively. Based on this, the study of the effect of multi-source interference and signal characteristics of the effect of high repetition frequency laser interference were studied. According to the simulation system testing, the results show that the multi-source interference and interference signal frequency modulation can effectively enhance the interference effect. While the interference effect of the interference signal amplitude modulation is not obvious. The research results will provide the evaluation of high-frequency laser interference effect and provide theoretical references for application of high-frequency laser interference system.
