Utilizing polarimetric information in sea ice charting will increase the efficiency and exactness of the maps. The number of classes used in the segmentation has shown to be of significant importance.

    Beyond the Sea of Ice is the first book in a prehistoric series by William Sarabande. As the first book, it is of course where you should start reading, as it introduces all of the characters. Lonit, Torka, and Torka's old father (Umak, who is 45 and considered old by the prehistoric standards) are the only survivors of a tribe who encountered 4/5. and sea ice classification. The potential of polarimetric interferometry for vegetation parameter retrieval was also assessed and demonstrated. A literature review on classification techniques for polarised SAR data was undertaken. The objective of this review was to choose the most promising techniques prior to their evaluation for land and Cited by: 4.

Here, the purpose is to relate sea ice characteristics and processes to active polarimetric signatures of sea ice through the development of a model based on sea ice properties. This is presented in a series of two papers: part 1 discusses the theoretical model. The C-band synthetic aperture radar (SAR) data from the Bohai Sea of China, the Labrador Sea in the Arctic and the Weddell Sea in the Antarctic are Polarimetric signatures of sea ice.

Discrimination of sea-ice types has conventionally been accomplished using various combinations of linearly polarized backscatter coefficients (Gupta and others, ). Radar backscatter of sea ice depends on. Polarimetric Analyses for Sea-Ice. The complex data can also be used to generate polarimetric signatures as well as polarimetric parameters which can be used to aid in interpretation and understanding of the scattering mechanisms.

Polarimetric discriminants can also be generated and used for classification purposes. Sea-ice classification methodologies for polarimetric SAR's are being developed and the results are demonstrating improved separability with the polarimetric response at both C- and L-bands.

An example for C-band data acquired by the CV off PEI in Marchis provided in Figure snow (characterized by low ZDR) are replaced by pristine ice crystals (characterized by high ZDR).

First three types of polarimetric signatures (1 – 3) are described herein in more detail. Refreezing signature 2.
