Abstract
This paper introduces outline of Japanese high-resolution earth observation satellite called ALOS, which NASDA plan to launch in 2002. Main mission objectives comprise DEM generation for GIS, environmental and hazard monitoring. NASDA have completed the investigation of users' requirements and preliminary design of hardware for the ALOS. As a result, the ALOS will equip both optical and microwave sensors to fulfill the requirements. DEM will be generated by the optical sensor with stereoscopic observation capability by 'three-line-sensor' with 2.5 m resolution. Multi-spectral information will be acquired by AVNIR-II, a multi-spectral optical sensors with 5m resolution and 4 bands. The microwave sensor, a L-band synthetic aperture radar (SAR), which is a follow-on of the JERS-1/SAR, has capabilities of look-angle change and the ScanSAR mode.
