Brief description Airborne passive radiometer for high resolution soil moisture monitoring. The project proposes to create a novel technology to measure soil moisture. Accurate knowledge of soil moisture profiles at high resolution is important for sustainable land and water management including efficient irrigation scheduling and cropping practices. A passive multi-band soil moisture-measuring radiometer at L-, Ku- and Ka-bands is proposed. The radiometer comprises a three-band shared aperture antenna array, a receiving electronics, a digital controller and a data logger. The array antenna comprises dual polarised stacked patch elements. Beamforming networks form agile beams to scan the ground. Sensitive radiometer receivers apply brightness temperature downscaling for high resolution. The high-resolution passive radiometer would revolutionise airborne soil moisture monitoring by removing the mechanically steerable bulky and heavy scanheads.
