MODE OF OBSERVATION FOR AIR OBJECTS AND SURFACE ON THE BASE OF AN AIRBORNE RADAR

摘要

FIELD: the invention refers to radiolocation namely to radiolocation systems of observation for air situation and surface on the base of an airborne radar, working in the mode of a "real beam", with electronic scanning.;SUBSTANCE: the technical result is in increasing resolution along the azimuth and the angle of place in assigned section of distance with preservation of the regime of observation along the azimuth and the angle of the place and increasing accuracy of estimation of the amplitudes of signals in synthesized elements of resolution. The known mode is based on the work in the regime of "real beam" with electronic scanning, containing in forming of the matrix of radiolocation image of air situation or surface in sections of distance. At that at the expense of quick electronic switching of a radar beam the beam is displaced along the azimuth and the angle of the place line-by-line correspondingly to the value of n and m part of the width of the radiation pattern of the antenna in the surveillance zone, the amplitudes of the signals' reflections are measured at each i,j-position of the beam and out of these amplitudes the matrix of measurements y(i,j), of the summary channel, which is further processed is formed, additionally the matrix of measurements y^,(i,j), of the delivery channel is formed, then the received matrixes for each I,j-position of the beam are processed, At that the elements of the matrix y(y+k,j+1) and y^,(i+k, I+1)and y^,(i+k,j+1) are summed up with weights h(k,l) and h^,(k,1) and the amplitude x(I,j) is estimated, the indicated operations are repeated for all i,j in the surveillance zone and by this the matrix of value of amplitudes is received.;EFFECT: increases resolution along the azimuth and the angle of place.;3 dwg
