Vertical-Array-based Contour Reconstruction Algorithm for Airborne Weather Radar

Aiming at meteorological target, in this paper, a new contour reconstruction algorithm is proposed against the disastrous weather. The algorithm is capable of reconstructing the specific contour of meteorological target by exploiting vertical array of airborne weather radar system. First of all, Burg algorithm is utilized for the enhancement of beam spatial resolution in elevation dimension. Then, multi-beam algorithm is employed to form multiple beams and generate multiangle echoes, which further obtains more vertical contour information about weather scenario. Consequently the proposed algorithm, combining Burg algorithm and multi-beam algorithm, distinctly retrieves the vertical contour information and delivers a super-resolution behavior simultaneously. Using simulated radar data, the processing results demonstrate the validity of the presented algorithm. Compared with the so-called interpolation-based conventional methods, the proposed algorithm can achieve more comprehensive and accurate vertical contour reconstruction.
