The SIVAM airborne SAR system

In response to the significant task of mapping and monitoring the Amazon region, the System for Vigilance of the Amazon (SIVAM) program was initiated by the Brazilian government. One of the key elements of SIVAM is a group of three remote sensing aircraft, each equipped with a multi-mode synthetic aperture radar as the prime sensor. The SARs are extremely flexible and provide: multi-channel fully polarimetric SAR mapping modes, cross-track interferometric SAR modes, spotlight SAR, and wide area surveillance with ground moving target indicator (GMTI) capability.
