隐身目标的双基地雷达探测技术

Study on the detection technology of bistatic radars for stealthy targets

以F-117A作为典型的隐身目标,提出一种计算隐身目标双基地雷达探测区域的新方法。通过对指定的雷达警戒区域进行网格剖分,在不同的网格节点位置计算隐身目标的双站雷达散射截面,由双基地雷达方程出发,从能量角度得到雷达探测判定不等式,计算目标的雷达探测区域。给出了应用该方法的具体步骤,通过仿真实验证明了该算法的可行性。

A new method for calculating the detection coverage of bistatic radars for stealthy objects is proposed, by means of which the fighter F-117A is researched as a typical stealth object. At first the guard coverage is divided by rectangle grid. The bistatic radar cross section of the stealth object is calculated at different lattice nodes. The judging inequality of radar detection is gained in the perspective of energy based on the bistatic radar equation. Then the detecting coverage of bistatic radar in different baseline distance is calculated. The detailed process of this method is given. The simulation result proves the practicability of the proposed method.
