Research On Anti-angle Deception Jamming Technolog

Angle deception jamming is one of the commonly used jamming methods of laser-guided weapons in modern battlefields.This method forms by duplicating the guidance signal and uses false targets to interfere with the signal to make laser-guided weapons misjudge the target position or distance.Because this method has the advantages of low implementation threshold and good interference effect,it is widely used on various ground weapon platforms.In order to improve the accuracy and damage rate of laser-guided weapon systems in hitting targets,the analysis of angle deception jamming and the study of corresponding anti-jamming measures are of great significance to improving the anti-jamming capability of laser-guided weapons.In order to study the anti-angle deception jamming technology,this paper establishes the related index model of the angle deception jamming success rate from the angle deception jamming,and based on this model,studies a variety of anti-angle deception jamming technologies,and analyzes the effective factors of different anti-jamming measures.And the specific effect.At the same time,an anti-jamming scheme based on compound detection technology and jamming signal advance detection is proposed,and the feasibility of the scheme is verified through experiments and simulations.The main research contents are as follows:First,the success rate index of angle deception jamming is studied.Analyze the working principle and characteristics of angle deception interference,establish an angle deception interference index model,and summarize feasible anti-jamming measures based on the attacker based on the specific influencing factors in the model,which are laser coding technology,time wave gate technology,and composite detection technology.Regarding the laser encoding technology,the commonly used laser encoding technology and decoding technology are studied,and the specific anti-jamming ability of different encoding technologies is analyzed according to different decoding technologies,and the selection of laser encoding methods in different situations has certain reference significance.Aiming at the time wave gate technology,the anti-jamming success rate of the time wave gate technology to the angle deception interference under different conditions was simulated,and the time wave gate type,time wave gate width,guidance pulse signal interval error,interference pulse signal interval error,The relationship between the jamming error signal advance and the influence of various factors on the jamming success rate are studied.Finally,based on compound detection technology,an anti-jamming scheme based on compound detection technology and jamming signal advance detection is proposed.The feasibility and anti-interference effect of the scheme are verified by Labview experimental system and Monte Carlo simulation method.
