Abstract:
A model is developed to analyze propagation effects on space-based radars SBRs with pulse-Doppler processing and with a displaced phase center antenna DCPA for rejection of surface clutter. It is found that nuclear- distributed ionospheric effects can significantly affect radar performance. Depending on the radar design parameters, similar, but less severe, problems may also occur in ambient auroral and equatorial ionospheres. The ionospheric effects degrade the DPCA clutter rejection and target Doppler processing functions of the radar.
