Zusammenfassung:FIELD: physics.SUBSTANCE: invention relates to the radar methods of moving and stationary surface objects their coordinates and motion parameters detecting and determining at line-of-sight distances of up to 800 km using the airborne radars. This result is achieved by means of the radar antenna beam movement in the azimuth and elevation planes due to the fact that the radar is placed on the rotating around its longitudinal axis vertical launch and flight rocket, allowing the radar vertical movement relative to the Earth around the rocket movement axis, allowing the antenna beam rotation along the spiral line synchronously with the radar rotation speed around the movement axis, at that, ensuring the coverage sector changing towards the greater range synchronously with the radar lifting height, and implementing the method device is placed on the vertical launch and flight rocket with rotation around its longitudinal axis radar, at that, the radar antenna is made in the form of a rectangular antenna web with the AFAR beam electronic control, placed under the radio transparent fairing along the rocket side surface, whose dimensions in the transverse plane are not more than 15 wavelengths of the radar operating range minimum frequency, and in the longitudinal rocket plane are not more than 150 wavelengths of the radar operating range minimum frequency, consisting of placed along the antenna length separate receiving and transmitting modules, sequentially switched on along the antenna length as the rocket is lifting. At that, the radar is made with possibility of operation both in the coverage mode and in the synthesized antenna aperture mode.EFFECT: achieved technical result is increase in the radar-visible on the sea surface objects detection range, increase in their coordinates and motion parameters determining and this data transmission to receiving points accuracy.4 cl, 1 dwg Изобретение относится к радиолокационным способам обнаружения и определения подвижных и неподвижных надводных объектов, их координат и параметров движения на дальностях прямой видимости до 800 км с использованием радиолокаторов на летательных аппаратах. Достигаемый технический результат - повышение дальности обнаружения радиолокационно-видимых на морской поверхности объектов, повышение точности определения их координат и параметров движения и передачи этих данных на приемные пункты. Указанный результат достигается путем перемещения луча антенны радиолокатора в азимутальной и угломестно
