Book Description
A multiband microwave polarimetric scanning radiometer (PSR) has been constructed for airborne observations from the NASA DC-8 airborne platform. The primary application of the PSR is the development of optimal spaceborne bard ware configurations and retrieval algorithms for passive wind. vector sensing over the ocean surface. Four radiometers, operating at 10.7, 18.7, 37, and 89 GHz, each measure the first three modified Stokes' parameters (T(sub upsilon), T(sub h), and T(sub u). A gimbaled mechanism allows observations at any incident angle within a cone of 700 half angle around nadir. The PSR's four radiometers and two axis scanning capability will provide unique polarimetric data for microwave emission studies of both ocean and land surfaces, as well as atmospheric clouds and precipitation.

Book Description
The Airborne Polarimetric Microwave Imaging Radiometer (APMIR) has been developed at the Naval Research Laboratory. This instrument was designed primarily as a calibration tool for satellite sensors. As such, the system design began with a challenging error budget. The design and construction followed from the error budget. The system has flown several times. This paper focuses on the design of the instrument and preliminary results.

Book Description
In this thesis, we present analytical models developed to account for platform attitude changes on measured ocean microwave brightness temperature collected by a conically scanning radiometer. Data processing procedures for removing unwanted variations in ocean brightness temperatures are outlined. The analytical models are validated by making comparisons between modelled and measured Tb's obtained by the Conically Scanning Two-Look Airborne Radiometer (C-STAR). Results demonstrated that the analytical Tb model can accurately predict the measured polarized Tb's under actual flight conditions.

Book Description
This book demonstrates the capabilities of passive microwave technique for enhanced observations of ocean features, including the detection of (sub)surface events and/or disturbances while laying out the benefits and boundaries of these methods. It represents not only an introduction and complete description of the main principles of ocean microwave radiometry and imagery, but also provides guidance for further experimental studies. Furthermore, it expands the analysis of remote sensing methods, models, and techniques and focuses on a high-resolution multiband imaging observation concept. Such an advanced approach provides readers with a new level of geophysical information and data acquisition granting the opportunity to improve their expertise on advanced microwave technology, now an indispensable tool for diagnostics of ocean phenomena and disturbances.

Book Description
This first comprehensive review of airborne measurement principles covers all atmospheric components and surface parameters. It describes the common techniques to characterize aerosol particles and cloud/precipitation elements, while also explaining radiation quantities and pertinent hyperspectral and active remote sensing measurement techniques along the way. As a result, the major principles of operation are introduced and exemplified using specific instruments, treating both classic and emerging measurement techniques. The two editors head an international community of eminent scientists, all of them accepted and experienced specialists in their field, who help readers to understand specific problems related to airborne research, such as immanent uncertainties and limitations. They also provide guidance on the suitability of instruments to measure certain parameters and to select the correct type of device. While primarily intended for climate, geophysical and atmospheric researchers, its relevance to solar system objects makes this work equally appealing to astronomers studying atmospheres of solar system bodies with telescopes and space probes.
