Beamforming P-band synthetic aperture radar for planetary applications

Abstract

The Space Exploration Synthetic Aperture Radar (SESAR) is an advanced P-band beamforming radar instrument concept to enable a new class of observations suitable to meet multiple Decadal Survey science goals for planetary exploration. The radar is capable of providing unprecedented surface and nearsubsurface measurements at full polarimetry and fine (meter scale) resolution, and achieves beam agility through programmable waveform generation and digital beamforming. The radar's highly flexible modular architecture employs a novel low power, lightweight design approach to meet stringent planetary instrument requirements, all while minimizing cost and development time.

Miniaturized P-band beamforming synthetic aperture radar transceiver

“…A study conducted By NASA GSFC, Instrument Design Lab (IDL) (May 2013) concluded that the development of a compact, lightweight and power efficient radar transceiver module was a critical and necessary step in the implementation of this type of spaceborne SAR instrument For this reason, we have developed a prototype miniature Pband radar transceiver, directly applicable to two concepts for future spaceborne missions: The Carbon and Ecosystem Structure Agile SAR (CEASAR), and Space Exploration SAR (SESAR).
