In spite of variance in the SIR transmit power, end-to-end transfer functions generated from either point targets or area-extended targets were found to yield close agreement for a given pass, indicating that targets of known radar cross section can be used to   This paper provides an overview of existing literature on vessel/ship detection and classification from optical satellite imagery.

All of the imaging modes of the PALSAR, i.e., single, dual, and full polarimetric strip modes and scanning synthetic aperture radar (SCANSAR), were   1. Introduction. Land cover is defined as the physical composition and characteristics of land elements on the Earth surface (Cihlar, ).Since the distribution of land cover has significant impact on the climate and environment, mapping the land cover patterns from global, regional, to local scales is important for scientists and authorities to yield better monitoring of the changing :// Passive point targets such as trihedral and dihedral corner reflectors are commonly used for synthetic aperture radar calibration because of their large radar cross section and wide radar cross SPOT-6 and SPOT-7 Commercial Imaging Constellation.

This area of research has emerged a decade ago, with the increasing availability of large-scale anonymized datasets, and has grown into a stand-alone topic. We survey the contributions made so far on the social networks that can be constructed with such data, the study of personal mobility, SPIE Digital Library Proceedings.
