We aim to select the range of frequencies where the medium parameters have less effects on the scattered waves, and as a result we achieve high precision of computed radar cross section (RCS). Ideal object detection can be obtained through calculation of RCS assuming a plane wave incidence in the far field. Numerical results are conducted to investigate effects of medium characteristics and target configuration on its RCS. We postulate convex illumination region of partially convex contour. Targets are taking fairly large sizes in the range of five wavelengths to suit the practical dimensions of objects such as aircraft. In this work, waves propagation from targets in free space and random medium are considered while assuming E polarization of incident wave.

频率选择以避免对平面E波极化的导电物体的RCS产生中等影响

我们旨在选择频率范围，在该范围内，介质参数对散射波的影响较小，因此，我们实现了计算雷达横截面（RCS）的高精度。假设在远场中有平面波入射，则可以通过计算RCS来获得理想的目标检测。进行了数值结果以研究介质特性和目标配置对其RCS的影响。我们假设局部凸轮廓线的凸照明区域。目标在五种波长范围内采取了相当大的尺寸，以适应飞机等物体的实际尺寸。在这项工作中，在假设入射波为E极化时，考虑了从目标在自由空间和随机介质中传播的波。
