基于经度切割的雷达网威力模型及算法

Longitude Incision Based Radar Net Coverage:Model and Algorithm

针对雷达网探测威力范围解算中计算量大、速率低、精度差的问题,建立了3种程式雷达的垂直威力模型,并采用经度切割方法,建立了大地坐标系下的经纬度平面威力模型。将雷达网探测区域按等经度间隔切割成若干条块,形成条状雷达网,将网内各部雷达的经纬度平面威力投影到条状雷达网中,建立了经纬度雷达网威力条块模型,并给出了切割算法。通过30部雷达构成的雷达网仿真表明,该方法将两维数据量降为一维,减少了计算量,提高了速率,解决了复杂遮蔽边界问题,求得的球面面积更加准确,解决了雷达网威力解算问题。

Current radar net coverage calculation has such deficiencies as huge calculation amount,low velocity and low precision.To solve the problems,the radar models of vertical coverage of three frequency bands are built,and the planar coverage model in geodetic coordinates is built by using the longitude incision method.The detection area of the radar net is incised into a couple of strips with the same longitudinal intervals so that a strip-shaped radar net is formed.The planar coverage of each radar in the net is projected onto the strip-shaped radar net.The strip-shaped model of radar net coverage is built,and an incision algorithm is given.A simulation was carried out on the radar net composed of 30 radars.The result shows that the proposed method reduces the two-dimension calculation amount to one dimension,which lowers the calculation amount,improves the velocity,solves the complex problem of masking boundary,acquires a more accurate spherical area,and solves the problem of the calculation of radar net coverage.
