一种用于干扰效果评估的闭环制导模拟方法

A Closed-Loop Guidance Simulation Method Used in Jamming Effect Evaluation

针对干扰效果评估需求,提出了一种简便易行的闭环制导模拟方法,即将导引头装在飞艇上,利用导引头测量输出的目标信息,按照导引律的要求,实时引导和控制飞艇向目标方向做制导飞行,以模拟闭环制导控制过程。利用电视导引头搭载飞艇,设定直接瞄准法导引律,完成了多个航次的闭环制导飞行试验。结果表明:飞艇飞行航迹与直接瞄准法导引律要求的理论航线基本一致,飞艇纵轴与目标视线的夹角以及导引头测量输出的离轴角均小于1°,也满足直接瞄准法导引律的要求,从而初步验证了所提出闭环制导模拟方法的可行性。这种作制导飞行的飞艇和导引头,可形象直观地演示、验证干扰效果。

A simplified and convenient closed-loop guidance simulation method is proposed to meet demands of jam- ming effect evaluation. A seeker is mounted on an airship and the airship is steered by target information produced by the seeker according to a guidance law to make a guidance flight in order to simulate the closed-loop guidance and control process. Guidance flight tests are completed with an airship loaded with a TV seeker adopting a direct aiming guidance law. Test results show that the airship flight path is consistent with the theoretical one for the direct ai- ming guidance law. Both the angle between the airship longitudinal axis and the line of sight and the off-axis angle of the seeker are less than 1~. This is consistent with the direct aiming guidance law and verifies feasibility of the method. The seeker-guide＆airship approach can be used in visualized demonstration and validation of jamming effect.
