Abstract: A signal processor 2 is configured so as to compensate for a peak shift of the distance between an SAR sensor 1 and a target, the peak shift occurring in the received signal subjected to range compression performed by an image reconstruction processing unit 14 due to a movement of the SAR sensor 1 during a time period until a reflected wave of a pulse signal is received by the SAR sensor 1 after the pulse signal is emitted from the SAR sensor 1. As a result, even when the SAR sensor 1 moves, an SAR image in which no azimuth ambiguity occurs can be reconstructed.

Abstract: A capless refueling mechanism includes a fill opening side shut-off valve disposed near the fill opening, and a fuel tank side shut-off valve disposed nearer to a fuel tank than the fill opening side shut-off valve. The refueling auxiliary device has a guide pipe section and a funnel section, and pressing of the fill opening side shut-off valve and the fuel tank side shut-off valve via an end of the guide pipe section causes a valve element to be moved away from a seat portion and insertion of a nozzle into the funnel section allows refueling. The outer circumferential surface of the guide pipe section is provided with an enlarged diameter section that regulates a valve opening degree of the valve element of the fuel tank side shut-off valve.
