Abstract

The Phased Array type L-band Synthetic Aperture Radar (PALSAR) on the Advanced Land Observing Satellite (ALOS) is considered to be one of the follow-on sensors of JERS-1 SAR. PALSAR is designed to achieve high radiometric performance as well as observation flexibility, in addition to the data continuity of JERS-1. It has a beam steering capability using an active phased array antenna, and a multi-polarization capability. In order to achieve high radiometric performance, the system parameters have been carefully designed, and some internal calibration procedures have been investigated. Based on the current design, PALSAR can acquire the data from 8 to 60 degrees of incidence angle. A noise equivalent backscattering coefficient is from -30 to -25 dB depending on the incidence angle. The required radiometric stability is within 1 dB over one scene. The status of development is currently the Bread Board Model (BBM) phase, and NASDA has manufactured the antenna system and tested it both electronically and mechanically. This paper describes the PALSAR system design as well as some results from BBM development.
