Using A 1-Kilowatt Power Amplifier For SAR Remote Sensing In P-band

In order to better understand the earth’s global carbon cycle, NASA and ESA have implemented different programs with the objective to make scientific measurements of the earth’s biomass. NASA utilizes an airborne synthetic-aperture radar (SAR) system operating in L-band, while ESA uses a GaN based system. This white paper presents a 2-stage, 40 dB gain, 1 kilowatt transmitter pallet as an alternative solution for ground-penetrating SAR applications in P-band.
