Abstract:
The Advanced Land Observing Satellite (ALOS) was launched by the Japan Aerospace Exploration Agency (JAXA) on January 24, 2006. In addition to two optical instruments (PRISM and AVNIR-2), ALOS carries an L-band polarimetric Synthetic Aperture Radar (PALSAR). As the successor of the JERS-1 satellite (1992-1998), PALSAR does not only provide enhanced sensor performance, but also features a novel global mission concept. Abandoning traditional, local-focused instrument operations, JAXA has implemented a comprehensive acquisition strategy, in which geographical region, sensor mode, acquisition timing and repetition frequency, are fixed in advance to achieve spatially and temporally consistent, global coverage on a repetitive basis, at the same time as reducing programming and user conflicts.
