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.
Analog-to-digital conversion, broad-beam antenna pattern, CW radar, digital filtering, Doppler radar, fast Fourier transform, flight data, radar backscattering cross section, reflectivity, remote sensing, scatterometer radar, spectral sign sensing, terrain reflectivity.
