Through analyzing the characteristics of wave gate setting and high-frequency laser active deception jamming of the seeker of laser semi-active guidance weapon,a scheme of counter high-frequency laser jamming is proposed by way of judging and sampling out of wave gate and comparing and eliminating in wave gate.

A novel method to detect and track small moving point target in image sequence is proposed in this paper,based on combination of the correlation of multi-frames and wave gate techniques.

On the basis of above,we analyzed the present situations of counter active deception jamming of terminally laser-guided shell,and emphasized to analyze selecting effect of wave gate to counter high pulse repetition frequency jamming,anti-jamming capability of transponder jamming and anti-jamming measures in tactics of laser-guided weapons application.

An full-automatic light adjustment method based on technology of signals selective gate;

According to the semi-active laser guidance weapon s technology status that its pulse repeating frequency coding is easily interfered,the possibility of high repetition rate laser interference with semi-active laser guided weapons operating based on real-time gate signal was studied.

This article brings up the method on the checking consistency for filtering nonsynchronous radar signal,which is used on the condition of the anti-radiation missile(ARM) system cannot producing the select gate for tracing target.
