FIELD: radio engineering.
SUBSTANCE: invention relates to space systems for remote sensing of the Earth based on radars, including using aperture synthesis technology. The result is achieved by the fact that a device for surveying the Earth's surface by a spacecraft is proposed, including a radar consisting of an antenna with a reflector, a feed in the form of a multi-horn linear antenna array, a rotating device for the reflector in roll, a receiving-transmitting path, an on-board control complex, characterized in that the transmitting path contains sequentially introduced electronic blocks of a radiated pulse signal shaper, a power divider, at least 15 power amplifier blocks and a power summing block controlled by the level control unit signal directly or through a controller.
EFFECT: flexible reduction in energy costs when obtaining an image of the same quality level under different shooting conditions - shooting mode, nature of the underlying surface and shooting elevation (roll) angle.
