摘要
用FDTD法对船目标的RCS进行了理论计算和分析。为验证计算结果 ,在几个频率上对船目标的RCS进行了测试。在高频段 ,由于回波中可能包含各种干扰 ,如周围环境的反射、地网的损耗等 ,即使有足够强的目标回波 ,也难以测试到较精确的RCS。针对这种问题 ,介绍了一种测试方法 ,该方法消除了外界其他因素的干扰。
The target RCS is measured, calculated and analysed by FDTD method. Because the returning signal includes much interference in HF, it is difficult to measure target RCS precisely even if the returning signal is stronger. In the light of these questions, a method of eliminating outside interference is described. A target is measured with the method and the results are compared with the calculation
