摘要

To provide a synthetic aperture radar technology that establishes both a high signal-to-noise ratio and a high resolution, does not require a mechanical or electric mechanism for controlling the direction of an irradiation beam, and achieves the simplification of a circuit and a cost reduction of a system.SOLUTION: The present disclosure is a synthetic aperture radar device 1 including: a chirp pulse generation unit 11 for generating a chirp pulse for range compression of a synthetic aperture radar; an antenna unit A that, in radiating the chirp pulse generated by the chirp pulse generation unit 11, changes the direction of an irradiation beam to an azimuth direction in accordance with the frequency of the irradiation beam according to an original directional characteristic without performing mechanical and electronic directional control; and a reflection signal receiving unit 12 for receiving a reflection signal reflected from a target T.SELECTED DRAWING: Figure 5
