Guide head control method for predicting target position

Abstract

The invention discloses a guide head control method for predicting the target position, and belongs to the technical field of a guide head control method. The method comprises the following steps of after a missile is emitted, calculating a prediction position [XT YT ZT] of a target in a three-dimensional coordinate system; performing calculation according to the prediction position of the targetto obtain two framework angles, i.e., a pitching framework angle x' and a yaw framework angle theta' when the guide head tracks and locks the target; comparing the pitching framework angle x' and theyaw framework angle theta' obtained through calculation with a practical pitching framework angle x and a yaw framework angle theta of the guide head in the missile flight process so as to judge whether the guide head tracks a wrong target or loses the correct target or not in the missile flight process. The method has the advantages that according to the self posture information of the guide headand the missile position posture information, the target information tracked and locked by the guide head before the missile emission is combined for predicting and judging the target information tracked by the guide head after the missile is emitted; whether the tracked target is correct or not is confirmed; and the guide head is enabled to capture the correct target.

Description

technical field [0001] The invention belongs to the technical field of seeker control methods, and in particular relates to a seeker control method for predicting target positions. Background technique [0002] The seeker is the core component of precision-guided weapons, and its core task is to continuously and effectively lock the target, especially for missiles that are locked before launch and cannot be manually intervened after launch. Since the missile adopts a short-term high-thrust launch scheme, the launch impact is relatively large. During this process, the complex optical circuit of the seeker may be affected. Once the relative positions of the components inside the optical system change slightly, it will seriously affect Tracking and locking of the seeker to the target. If the seeker loses or follows the wrong target, the flight mission will fail. Therefore, it is necessary to adopt a seeker control method to complete the recapture of the correct target and red...
