FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relates to radar ranging and intended for construction of surveillance radar stations with digital antenna arrays. In each beam pattern (BP) bearing position in transmission mode the digital antenna array generates radial transmitting BP in the elevation plane, in the reception mode, in the case of receiving rays placement in the square grid nodes, generating the two receiving multi-beam BP in the elevation plane with the needle-shaped beams, at that, the neighboring beams in the BP are overlapped in the L level, equal to half the power from the maximum, placing the first and second BPs parallel to each other so, that the beams with the same elevation coordinates were overlapping in the L level, and the transmitting beam bearing coordinate corresponded to the first and second BPs beams intersection line. In case of the receiving beams placement in the triangular grid nodes, generating the three receiving multi-beam BP in the elevation plane with the needle-shaped beams, at that, the adjacent beams in the BP are overlapping in L level, placing the second and third BP parallel to each other so, that the beams with the same elevation coordinates were overlapping in the L level, and the transmitting beam bearing coordinate corresponded to the second and third BPs beams intersection line, combining the first BP beams maxima location line with the second and third BP beams intersection line, combining the second and third receiving BPs beams maxima elevation coordinates with the first receiving BP beams intersection line, during the objects detection, measurement of their range and elevation coordinates each the receiving beams adjacent pairs single-pulse signal processing method is used.

EFFECT: increase in the object elevation coordinate measurement accuracy by using the single-pulse measurement method instead of the maximum method.
