摘　　要：利用插值方法计算双基地雷达散射截面积,由此建立压制干扰条件下的双基地雷达探测范围方程。将导数取零作为曲线取极值的必要条件,推导出双基地雷达警戒区域边界解析表达式。在估算警戒区域面积的基础上,提出双基地雷达盲区的构造算法,并给出网格点上双基地雷达探测高度最大值与最小值的计算方法。利用OpenGL绘制双基地雷达三维探测范围。实验结果表明,该方法能在微机上实时地显示压制干扰条件下双基地雷达三维探测范围的动态变化。Computing bistatic radar cross section by linear interpolation,the calculation equation of bistatic radar detection range under condition of suppression jamming is presented.If curve gets extreme value,the derivative is zero.The analytical formula of bistatic radar alert region edge is deduced by the principle.Based on the calculation of the edge,the algorithm for the construction of bistatic radar shadow is investigated and the mathematical model of bistatic radar detecting maximum and minimum altitudes at a grid point is put forward.3D visualization of bistatic radar coverage is implemented with OpenGL.Simulation result shows that the 3D coverage of bistatic detection radar affected suppression jamming is visualized vividly in real time.
