| 摘 要： | 雷达目标散射截面是衡量目标散射特性的重要参数，特别是处于地波雷达谐振区的船只后向散射特征，在雷达威力估计、舰船目标检测、类型识别等方面非常有用。为了有效预估高频地波雷达海面船只目标的散射特性，提出一种基于有限元建模的高频地波雷达谐振区舰船目标RCS计算方法。该方法首先利用3D-MAX对典型船只进行建模，然后利用有限元方法对船只模型进行网格剖分，最后计算出谐振区舰船目标RCS值。通过对仿真结果的分析表明，谐振区目标RCS受雷达频率、方位角等因素影响明显。

| Abstract: | Radar cross section is an important parameter to measure the target scattering characteristics.Especially,radar backscattering characteristic of the vessel is useful in the radar power estimation,ship detection and identification in the resonance region.To estimate the scattering characteristic of ship targets in HF band,a calculation method which is based on a finite element modeling is proposed.This method is proved to be suitable for ship RCS calculation in resonance region.Surface modeling software 3D-M... |
