Abstract
The searching phase of TV guided missile is usually divided into three different stages as the navigation, homing and terminal guidance. In this paper, guidance laws in different phases are analyzed. To solve the problem of target acquisition, signal following and navigation precision during the period of navigation, methods of integrated guidance with three geostationary satellites orientation and INS in high dynamic circumstances are put forward. The mathematics models of pre - guiding and searching are established corresponding to the traits of smaller TV seeker instantaneous field, limited shooter reacting velocity, low hunting speed and narrow searching area. The compound guidance methods which integrate the tracking and the proportional in terminal phase are raised in order to increase the guiding precision and to decrease the undershoot value. Experiment shows that the guiding precision is raised by a long way.CLC number: TJ765.4+3 Document Code: B
