MAPSAR [INPE]
MAPSAR (Multi-Application Purpose SAR) is a brazilian SAR (Synthetic Aperture Radar) mission for Earth Observation. It will feature a sensor system for cartography, forestry, geology, geomorphology, hydrology, agriculture, disaster management, oceanography, urban studies and security.
To accomplish the overall requirements, an L-band SAR has been chosen as the only payload of a small satellite. The key component of the SAR instrument is the SAR antenna, which is designed as an elliptical parabolic reflector antenna with dimension of approximately 7,5 m (azimuth) × 5 m (range). L-band (high spatial resolution, quad-pol) has been selected for the SAR sensor as optimum frequency accounting for the majority of Brazilian and German user requirements.
The satellite was to be based on INPEīs Plataforma Multimissão (Multi-Mission Platform, MMP).
The MAPSAR effort seems to have been cancelled around 2009.
