对激光测距机干扰效果的评估方法研究

研究了光电干扰设备对激光测距机干扰效果的评估方法。区分激光距离欺骗干扰和激光致盲干扰，分别分析了它们对激光测距机的干扰机理，提出了相应的干扰效果评估准则。对激光距离欺骗干扰效果的评估，可以根据实施干扰后测距机的测距误差是否超出无干扰时的正常测距精度的三倍判定干扰是否有效，并依据干扰成功率的大小将干扰效果划分为若干等级。激光致盲干扰设备对测距机的干扰效果可以依据致盲激光对测距机测距精度、测距能力的影响程度划分为四个等级。

The Evaluation of Electro-optical Jamming Effectiveness on Laser Rangefinder

A method for evaluating the effectiveness of electro-optical jamming device on laser rangefinder was proposed in this paper.The evaluation rules of jamming effectiveness for laser range deception jamming and laser blinding jamming on laser rangefinders were presented in detail.For laser range deception jamming,whether the ranging error of a laser rangefinder under jamming is greater than three times its ranging accuracy(standard deviation) without jamming is proposed as the criterion for whether the jamming is effective or not.The jamming effects can be graded into several jamming rates according to the jamming success rates.For laser blinding jamming on a laser rangefinder,the jamming effects can be graded into four jamming rates according to the degrees of damage to the ranging accuracy or ranging capability of the laser rangefinder.
