| Overview
PALSAR is an active microwave sensor for cloud-free and day-and-night land observation and provides higher performance than JERS-1's SAR.This sensor has a beam steer able in elevation and the ScanSAR mode, which allows us to obtain a wider swath than conventional SARs. The development of PALSAR is a joint project between JAXA and the Japan Resources Observation System Organization(JAROS).

The left image shows the deployment test of the antenna. The antenna consists of 4 flat boards, 3.1m by 2.2m each, and they are folded at launch. The antenna will be deployed approximately 2 days after the launch of ALOS. Since it is designed to deploy under weightless conditions, the test was conducted by hanging the whole antenna so as not to be affected by gravity. |
