This brief presents a novel nonlinear adaptive line-of-sight (ALOS) guidance law for path following, compensating drift forces due to wind, waves, and ocean currents. The ALOS is proven have uniform semiglobal exponential stability (USGES) properties during straight-line following at constant speed. performs similar the classical integral (ILOS) ILOS laws when sideslip angle nearly constant. la...

The ALOS Kyoto & Carbon Initiative is an international endeavour initialized by NASDA, with the main objective to support information needs raised by the UNFCCC Kyoto Protocol and by the international global carbon cycle science community, by provision of systematic, consistent, repetitive and regional scale data of the global forest cover. Of central importance for the Initiative is a Dedicate...

Among the several applications that will take advantage of the newly available data from the ALOS PALSAR instrument, considerable interest is in the peculiar features that derive from the penetration and polarimetric capabilities of the system. These capabilities, new for a single spaceborne sensor, need specific software tools for the processing of the different acquisition modes. This paper p...

 SIR-C quad-pol MLC data acquired in 1994 and ALOS PALSAR quad-pol and dual pol SLC data acquired in 2006 and 2007 over several Indian sites have been processed using PolSARpro software for classification of various land features. The land features include ocean, clear water, settlements, agriculture fields, arid lands, grown and young forest, hilly terrain, mangrove forest, etc. Both unsuperv...

A study on sea oil slick observation by means of Lband polarimetric synthetic aperture radar (SAR) data is accomplished. It is based on the different sea surface scattering mechanism expected with and without surface slicks. Polarimetric measurements are processed by means of a simple and very effective filtering technique which is electromagnetically based on the Mueller scattering matrix. Mor...

This report presents the polarimetric calibration results of ALOS/PALSAR and discusses a stability of polarimetric calibration parameters during the calibration phase of ALOS and an influence of Faraday rotation on them. PALSAR is the first spaceborne polarimetric L-band synthetic aperture radar and its polarimetric data is expected to be utilized in various remote sensing applications. However...
