A Stable Target Tracking Method for Radar Antenna at High Elevation Angle
[Purposes]Aiming at the phenomenon of abnormal jitter and dynamic lag of the antenna caused by the existence of secant compensation in the state of high elevation overhead tracking,a theo-retical analysis method of the track before the high elevation tracking measurement task of the measure-ment and control equipment is proposed.[Methods]The secant compensation principle is used to ana-lyze the target track in the high elevation state.Combined with the antenna tracking performance,the pre-judgment is carried out to determine the section where the antenna can maintain the tracking state in the high elevation tracking measurement task,which provides theoretical support for the formulation of the antenna acquisition and tracking strategy in the transmitting section,and obtains the measurement data as much as possible.[Findings]Through the analysis of the data in this paper,the paragraphs in which the antenna can maintain the tracking state in the high elevation angle tracking measurement task are determined in advance,which is more meaningful than the previous prediction judgment method without data support.Taking the data in this paper as an example,the timing of equipment switching tracking state can be accurately judged,and about 8 seconds of effective data are obtained compared with the previous judgment method.[Conclusions]This method can provide theoretical support for the target acquisition and tracking strategy of the antenna in the high elevation over-the-top tracking state.
