symmetry

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.

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。

For an image guided missile,adopting guided search can increase the probability of target entering the instantaneous field of view of the seeker,but it may cause dissymmetry of the monitor image under some conditions.
