Anomalous propagation of radar signals - challenges with clutter

Abstract

Existing algorithms are tested and new ones are developed for the automated identification of radar echo features, with particular emphasis on recognition and removal of ground clutter and anomalous propagation (AP) echoes. A Zero Doppler velocity (ZDV) is found to be very valuable indicator of ground clutter and AP echoes, along with vertical reflectivity gradients (VRG) and the horizontal variability and texture of the radar reflectivity field. VRGs proved to be quite good indicators even in AP embedded in rainfall cases, while the ZDV criterion tended to flag and/or remove precipitation echoes with no radial wind component and algorithm development based on the third criterion was not computationally economical.
