ABSTRACT:
A synthetic aperture radar apparatus comprising an altitude calculation device, and means to feed back altitudinal information obtained by the altitude calculation device, to a synthetic aperture radar device in the synthetic aperture radar apparatus at all times. Thus, an observational region is observed with the synthetic aperture radar device, while at the same time, the altitude of an artificial satellite is calculated by measuring the acceleration thereof in the altitude calculation device, the altitudinal information being continually fed back to an operation controller in the synthetic aperture radar device, whereby the synthetic aperture radar device is operated continuously and automatically.
