封面来自Bell’s SIO 报告的图片显示了飞行演示期间雷达地面杂波的一个极端例子,当时 APT 70 距离地面大约 200 英尺。随着飞机高度下降,虚假(ghost)雷达轨迹的数量也在增加。 本节介绍matlab中雷达工具箱在距离多普勒空间中计算平坦无特征表面的雷达散射截面。了解如何使用表面RCS来检查杂波的表现,分析表面目标的可探测...
This book provides a detailed description of some of the most widely used rational fitting techniques for approximation of frequency domain responses. The techniques are: Bode’s asymptotic approximation, the Levy method, iteratively reweighted least squ
在MATLAB中, 这种想法可以通过调用该函数的 rand (seed,s)格式来实现。 其中s是标量,可以通过不同的s值来改变机器随机数发生器的 种子数,s = 0则设回缺省值。如: rand (1, 4) ans = 0.2190 0.0470 0.6789 0.6793 rand (seed, 1) rand (1, 4) ans = 0.5129 0.4605 0.3504 0.0950 r 36、and (...
