针对导引搜索下不对称现象的搜索规律研究

Study on the Law of Searching Aimed at the Dissymmetry Effect in Image Seeking Adopting Guided Search

为了消除图像制导导弹在采用导引搜索时某些情况下监视器画面移动速度的不对称现象,找到了形成不对称现象的两个原因——视线角速度和导弹的前置速度,在此基础上对常规一字型搜索规律进行了改进,形成一种非对称一字型搜索规律.仿真结果表明,采用非对称一字型搜索规律能够消除监视器画面移动速度的不对称现象,从而更有利于射手对目标的识别和捕获.

To remove dissymmetry of the movement of monitor image under some conditions when image guided missile adopting guided search, two factors causing this dissymmetry are found, viz, the angular velocity of line of sight and the lead speed of the missile. According to the two factors the parallel search law is modified to form a new parallel search law based on dissymmetry. Simulation results showed that by adopting the dissymmetrical parallel search law dissymmetry of the movement of monitor image can be removed which is very helpful for the shooter to acquire and capture targets.
