对于雷达、声纳系统而言，宽带条件往往比窄带条件具有更广泛的适用性。这时目标常看作是具有多亮点空间结构的延展目标，宽带成像的目的是得到该空间结构。针对现有宽带成像处理手段，文中讨论了用于宽带成像的信号设计原则及方法。

For radar and sonar systems, wideband condition has more applications and suitability than narrowband condition. Under this condition, target is often taken as a multi spot space-spreaded target, and the goal of wideband imaging is to obtain the space structure. Focusing on existing means of wideband imaging, this paper discusses the principle and method of signal design used for wideband imaging.
