实现激光角度欺骗干扰的几个条件

构建了由机载激光照射吊舱指示地面目标,指引激光半主动制导武器进行攻击,地面激光干扰装备照射假目标实施有源角度欺骗干扰态势,并建立了数学模型;论述了保证有源角度欺骗干扰有效实施的3个主要条件,重点讨论了假目标满足大、小目标条件时激光干扰功率要求,并定义了两个参量:激光信号束散比β和目标面积比σ。

Some Conditions for the Realization of Laser Angle Deception Jamming

We establish a situation that the airborne optoelectronic pod directs the laser-guided weapon to attack the target on the ground and the laser jamming equipment jams it to achieve active laser angle deception jamming.A mathematical model is also established.The three conditions for ensuring the laser angle deception jamming are discussed.Emphasis is put on the power needed when the fake target is a small or big target.Two parameters are defined,one being β,the angle ratio of beam divergence of the jamming laser and guiding laser,the other being σ,the area ratio of the fake target and real target.
