Abstract:

A survey is made of major phenomena of the lower atmosphere and ionosphere which would introduce clutter and affect propagation in the 0.2-3.0 GHz frequency range in a space-based, ground-looking radar. Attenuation, refractive effects, and weather-related phenomena are included in the study. It is found that the major trade-off that must be made in the frequency range is the relative immunity of the low frequencies to weather related phenomena versus the relative immunity of the high frequencies to deleterious ionospheric effects.
