The Alberta Hail Studies S-band radar, which has a polarization diversity antenna and a dual channel receiving system, provides outputs from which the relative phase angle and the degree of correlation between the signals received on two orthogonal polarizations may be calculated. This report describes apparatus which accepts these radar outputs and generates from them quantized grey-scale levels for presentation of either the correlation or the relative phase information on a PPI-type display in real time. Circuit details and PPI photographs taken during a hailstorm are included.
