基于经度切割的雷达威力模型及算法研究

A Study on Model and Algorithm for Radar Coverage Based on Longitude Incision

针对雷达威力解算中计算量大、速率低、精度差的问题,提出了一种经度切割的威力解算方法。建立了3种程式雷达垂直威力模型,并以垂直威力上的高度层切线,建立直角坐标系下各个高度层的平面威力模型。将平面威力按等经度间隔切割成若干条块,建立大地坐标系下各个高度层的平面威力条块模型,给出经度切割算法。仿真结果表明,通过对平面威力进行经度切割,减少了计算量,提高了速率,解决了复杂遮蔽边界问题,是一种快速实用的解算方法。

The paper gives an algorithm base on longitude incision for radar coverage to overcome the deficiencies in account amount,velocity,precision in radar coverage calculation.The models of radar vertical coverage with three frequency bands,and planar coverage of per height level in rectangular coordinate were established.A method of longitude incision was given,which coverage was incised at regular longitude intervals,and the planar coverage model in geodetic coordinate were established.Simulation result shows that calculation amount is reduced,velocity is faster,the computing of terrain masking boundary is solved by longitude incision,and it is a practical and fast algorithm for radar coverage computing.
