摘要
舰船RCS是海上雷达系统探测回波强度的一个重要物理量,受多种因素影响,会呈现不规律的随机起伏。论文主要研究了粗糙海面的起伏特性、不同频率、不同极化方式以及不同入射方向的雷达入射电磁波对舰船RCS特性测量的影响,给出了粗糙海面的统计模型,运用时域有限差分法(FDTD)对舰船的RCS进行了计算仿真,研究结果为海面雷达的侦测提供了理论参考依据。
hip RCS is an important physical property of echo intensity in the detection of radar system,it is extremely easy to be affected by the rough sea surface,the testing environment and so on,ship RCS will fluctuate randomly. We researched the property of the fluctuating rough sea surface and the incident electromagnetic wave with different frequency and different polarization,they all can affect the ship RCS. Statistical model of sea surface is elaborated,FDTD is used in simulating ship RCS. The simulation results provide a theoretical reference for the detection of radar system used above the rough sea surface.
