JERS-1, launched in Feb 1992 and ended in Oct 1998, was a joint Japanese radar/optical mission with NASDA/JAXA lead. The overall objectives were the generation of global data sets with SAR and OPS sensors aimed at surveying resources, establishing an integrated Earth observation system, verifying instrument/system performances.

The mission applications focused on survey of geological phenomena, land usage, observation of coastal regions, geologic maps, environment and disaster monitoring and demonstration of two-pass SAR interferometry for change detection.
