Special Issue Information

Dear Colleagues,

Spaceborne microwave and millimeter-wave radiometers and scatterometers remain among the most valuable tools for accurate global measurements of the Earth's land, ocean surface, and atmospheric properties and processes. Numerical weather prediction and climate monitoring have, in the past 30+ years, come to depend on these sensors. At the same time, radio frequency and digital technologies have emerged which pose both a threat—from radio frequency inter inference (RFI)—and an opportunity in the form of new low-power RF and signal processing hardware with ever-greater capabilities at lower costs. In this Special Issue, we invite papers to discuss technology and engineering trends pertaining to the design and calibration of these sensors. Suggested subjects include, but are not limited to lightweight deployable antennas, RF topologies and internal calibrator circuitry, multiply redundant calibration schemes, and digital back-end designs.

Increasing attention is being paid to the monitoring of global change, and remote sensing is an important means for acquiring global observation data. Due to the limitations of the orbital altitude, technological level, observation platform stability and design life of artificial satellites, spaceborne Earth observation platforms cannot quickly obtain global data. The Moon-based Earth observation (MEO) platform has unique advantages, including a wide observation range, short revisit period, large viewing angle and spatial resolution; thus, it provides a new observation method for quickly obtaining global Earth observation data. At present, the MEO platform has not yet entered the actual development stage, and the relevant parameters of the microwave sensors have not been determined. In this work, to explore whether a microwave radiometer is suitable for the MEO platform, the land surface temperature (LST) distribution at different times is estimated and the design parameters of the Moon-based microwave radiometer (MBMR) are analyzed based on the LST retrieval. Results show that the antenna aperture size of a Moon-based microwave radiometer is suitable for 120 m, and the bands include 18.7, 23.8, 36.5 and 89.0 GHz, each with horizontal and vertical polarization. Moreover, the optimal value of other parameters, such as the half-power beam width, spatial resolution, integration time of the radiometer system, temperature sensitivity, scan angle and antenna pattern simulations are also determined.
