Abstract
A signal processoris configured so as to compensate for a peak shift of the distance between an SAR sensorand a target, the peak shift occurring in the received signal subjected to range compression performed by an image reconstruction processing unitdue to a movement of the SAR sensorduring a time period until a reflected wave of a pulse signal is received by the SAR sensorafter the pulse signal is emitted from the SAR sensor. As a result, even when the SAR sensormoves, an SAR image in which no azimuth ambiguity occurs can be reconstructed.
