Based on the lagrange - maxwell equation of electromechanical dynamics , the non - linear biaxial coupling electromechanical dynamic model is developed . taking some high - powered microwave antenna for example , the three - dimensional modeling software ( i - deas ) and the simulation software ( matlab ) are regarded as the main design platform , and the electromechanical simulation under the pid algorithm is done . the simulation results show that the tracking device of azimuth and pitching is plausible , and provide a theoretical foundation for vr study on target tracking systems 基于機電動力學的lagrange ? maxwell方程,得出了非線性的雙軸耦合機電動力學模型;并以某重型高功率微波天線為例,利用i ? deas三維建模軟件和matlab仿真軟件為主設計平臺,完成了基于pid控制算法的跟瞄系統(tǒng)的機電動力學仿真,仿真結果證明了方位俯仰跟瞄裝置的機電動力學模型的合理性,并且為目標跟瞄系統(tǒng)的虛擬現(xiàn)實研究提供了理論依據(jù)。
As a primary problem of ballistic target tracking which is a key technology in radar data processing , tracking initialization plays a very important role . the goal of this paper is to research on target tracking initialization for rapid target . the emphasis is how to select the size and the number of tracking gate 彈道目標的跟蹤是雷達數(shù)據(jù)處理的一項關鍵技術,航跡起始作為目標跟蹤的首要問題,重要性是不言而喻的。本課題的指導思想是:面向工程實際,針對快速目標的運動特點,研究快速目標的航跡起始問題。
