Two‐dimensional synthetic aperture millimeter‐wave radiometric interferometer for measuring full‐component Stokes vector of emission from hydrometeors

Abstract

Calculations of attainable values for space resolution and radiometric sensibility of a spaceborne two‐dimensional synthetic aperture microwave polarimetric interferometer are carried out. It is shown that for the most preferable Y‐shaped interferometer configuration, it is possible to achieve (within the transparency windows of waveband 3–22.5 mm) a space resolution of 0.5–1 km and a radiometric resolution close to 1 K at the receiver bandwidth of 100 MHz. For cross‐ and T‐shaped resolutions, values close to the above can be reached.

Optimal restoration of radiometric images in ultrawideband radiometric systems with multi-antenna array

“…When solving a considerable class of problems, it is required to form radiometric images (RMI) with a high resolution in spatial (angular) coordinates. Such RMIs are obtained with the aperture synthesis systems [1][2][3][4] realizing a basic state of the Van Cittert-Zernike theorem [2]. Such an approach is fruitful, but it doesn't follow from the solution of optimization problem and imposes restrictions on the bandwidth of the radiometer predetection section (RPS) (it is reasonable for narrow-band systems only).…”

Preface to special section: Remote Sensing of the Earth's Environment by Microwave Radiometers and Radar

“…[2003] presents a method to assess the performances of a space-borne interferometric radiometer measuring the brightness temperature of the Earth (ground and sea) surface. Kutuza and Zagorin's [2003] paper describes the design of an instrument for spaceborne applications. Rotbøll et al [2003] describe a fully polarimetric radiometer of the correlation type intended for L-band airborne measurements of polarimetric sea signatures.…”

Intensity and polarization of thermal radiation of three-dimensional rain cells in the microwave band

“…Due to this and other directions of research, interaction of microwave radiation with precipitations and clouds of various types is now extensively studied [3][4][5][6][7][8][9][10][11][12][13]. Many of them consist of non-spherical particles, having prevalent orientation like falling raindrops.…”
