Abstract :
An all digital method to produce radar reflectivity plots from analog flight data is presented. The method constitutes a qualitative and operational advance over existing methods. The data are audio-frequency Doppler information extracted from the terrain echo signal of a 13.3-GHz CW scatterometer radar.
