| | 講演要旨(英文) | | Through wall radar system is useful for non-destructive measurement in the building, such as structure imaging and rescue of the buried people. Through wall radar is based on Ultra-Wide Band signal transmission because of its several inherent advantages such as penetrating ability, high resolution, immunity to multipath and simple architecture. In imaging a target inside a wall, some phenomena deteriorate the target image like the reflection from the wall surface or velocity variation of electromagnetic waves by permittivity of the wall. In this paper, I will report the characteristic of the spiral antenna for UWB system, and its effectiveness for the through wall radar. |
