单基地雷达对隐身目标探测范围的研究

通过分析典型隐身目标的单站雷达散射截面,提出一种计算隐身目标雷达探测区域的新方法,由单基地雷达方程出发,从能量角度得到雷达探测判定不等式;采用一种新的雷达探测区域仿真计算的网格剖分方法,给出隐身目标探测范围的仿真计算流程。仿真计算了不同频段单基雷达对隐身目标的探测范围,验证了该方法的可行性。

A Study on the Detection Coverage of Monostatic Radar for Stealth Target

A new method for calculating the detection coverage of monostatic radar for stealth objects is proposed based on monostatic radar equation by studying the RCS of a typical stealth object.The judging inequality of radar detection is obtained from the energy in monostatic radar equation.The detecting coverage is calculated by a new method of lattice subdivision.The simula- tion process of calculating the detection coverage of stealth objects is described.The detection coverage of monostatic radar for dif- ferent frequency band is computed to check the feasibility of this method.The results of the simulation show that metre-wave mono- static radar is better than centimetre wave monostatic radar in terms of anti-stealth performance.
