Abstract: Systems and methods presented herein are generally directed to providing power to a radio frequency module of a radar antenna. For example, a system comprises a dedicated power cell that supplies a power signal and includes a dedicated solar power module that generates electrical energy for the power signal. The system also comprises a dedicated signal conditioner coupled to the power cell and to the radio frequency module, the signal conditioner conditioning the power signal for use by the radio frequency module. The radio frequency module receives conditioned power from the signal conditioner to use in processing a radio frequency signal. The radio frequency module may be a Synthetic Aperture Radar (“SAR”) that comprises one or more radiating elements to transmit pulsed electromagnetic energy for use in radar processing. The SAR may also comprise a receiver that receives the pulsed electromagnetic energy reflected from a target.
