| Outline of Final Research Achievements |
We developed frequency swept vibro-Doppler inverse synthetic aperture radar imaging method for an azimuth localization method of a target by using a fixed transmitter and receiver. For a derivation of proposed method, we use a ultrasonic wave as a sensing wave in a agar gel. In the case of an isolated target in agar gel, we can detect a target response at a proper position. However, in the case of a cut on the boundary between agar gel and water, we can not detect it the proper position. But, we can observe the reflection of the vibration wave from the cut beneath the sensor position. Therefore, we can clarify that the position of cut can be detected by moving the sensor position.
