基于目标静电场的水中兵器制导方法研究
|
摘要
如何在敌方目标的电场等效模型和所在海域深度未知的情况下,获得目标的速度和位置信息是当前水中兵器制导技术的一个难题.根据目标静电场的基本特性,提出了一种在目标静电场模型未知条件下求解运动目标速度和方向的方法.通过分析模型未知的目标的混合电偶极子电场分布,发现任意目标对称面上电场法向值为零,因此可以通过寻找此平面来实现对模型未知目标的制导.1:100的船模实验表明,此方法能够较为精确的确定未知模型目标的运动速度和方向,即使引入地形误差,精度也可达到97%以上,能够满足水中兵器制导的要求.
How to obtain target speed and location in the case of unknown equivalent electric model and unknown model number of layers of the environment is a difficult problem of the current water weapon guidance technology.Through the analysis of the basic characteristics of the target electrostatic field,a way to obtain the motional target speed and direction in case of the unknown target equivalent electric model is proposed.Through the analysis of the electrical field distribution produced by mixture electric dipole of unknown equivalent model,the electric field normal value of the target symmetrical plane was found to be zero.Therefore,we can achieve model unknown target guidance by finding this plane.1:100 ship model was used in laboratory experiment,and the results of the experiment shows that the target speed and direction of the unknown model can be obtained in this way.The accuracy reached more than 97%,even if the terrain error was introduced,which can meet the requirements of engineering applications.
