摘要
提出了一种计算双基地雷达探测区的新方法。其思路是,基于双基地雷达的雷达方程和干扰方程,通过比较双基地雷达与单基地雷达探测区求解的不同之处,引申出双基地角等值线的概念。分析得出,常规单基地雷达探测区上的任一点必然属于从雷达引出的某一条射线,而双基地雷达探测区上的任一点必然属于某一条双基地角等值线。以此为基础,最终计算出双基地雷达在无干扰和自卫干扰时的探测区,并通过仿真计算,验证了其可行性。
A new method for calculating the detection coverage of a bistatic radar is proposed. Based on radar equation and jamming equation of bistatic radar and by comparing the differences in the calculation of detection coverage between a conventional monostatic radar and a bistatic radar, the conception of bistatic radar angle isoline is presented. Then a conclusion is drawn that is, any point in the detection coverage of a bistatic radar belongs to a certain bistatic radar angle isoline, while a point of a conventional monostatic radar belongs to the radial drawn out from radar itself. Based on this conclusion, the detection coverage of a bistatic radar in jamming-free and SSJ circumstances is finally calculated. The simulation result proves the practicability of the proposed method.
