Based on theoretical deductions and data simulations , this dissertation analyzes properties of echo data in time domain , frequency domain and wavelet packet transform ( wpt ) domain . we also analysize properties of complex image data in image domain , image frequency domain and image wavelet packet transform domain . several methods are proposed for jamming suppression in signal domain and image domain respectively
本文在理论推导、数据仿真的基础上,分析了原始回波数据在时域、频域和小波变换域的特征以及复图像数据在图像域、图像频域和图像小波变换域的特征,提出了几种行之有效的信号域和图像域抑制方法。
