The radar monitoring technologies of the land surface constructed on the basis of the principle of synthesizing of an aperture of the antenna which, unlike traditional approach when synthesis of an aperture is carried out at progress of the phase center of the antenna, are formed on the basis of rotation of the phase center of the real antenna are considered. It is shown that in this case there is an opportunity to increase linear resolution capability of the radar on an azimuth when comparing with the radar station using the traditional procedure of synthesis of an aperture. And the necessary azimuthal resolution of the radar will remain invariable regardless of an angular position of the purpose concerning the line of a way of the RSA carrier. It allows to create the radar image (RLI) of the observed land surface with identical detailing in any angular direction concerning the line of a way of the carrier of helicopter type, including, and is strict in the area of its way. It is noted that forming of RLI of the land surface of high detail is possible both at the motionless carrier of helicopter type, and at its movement. The possible modes of functioning of the onboard radar of the carrier of helicopter type which can be implemented with use of this technology are considered. The results of modeling confirming advantages of the considered technology are presented.
