Aiming at meteorological target, in this paper, a novel 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 experimental results demonstrate the validity of presented algorithm. Compared with conventional interpolation-based and multi-beam methods, the presented algorithm can achieve more comprehensive vertical contour reconstruction.
