Analysis of Anti-jamming Time-gate Width for Semi-active Laser-guided Weapon
With the continuous development of active laser jamming technology,the attack accuracy of semi-active laser guidance weapons has been seriously affected.Coding technology and time-gate selection technology are common and effective anti-jamming measures.In order to increase the dif-ficulty of active laser interference,the width of the time-gate should be as narrow as possible.How-ever,the width of the time-gate cannot be infinitely small due to the influence of laser pulse trigger control accuracy,Doppler frequency shift of moving objects,etc..In this paper,the ideal width range of time-gate is obtained by analyzing the influence of various factors.
