The Brazilian-German MAPSAR (Multi-Application Purpose SAR) mission is a proposal for a light and innovative L-band SAR sensor, based on INPE´s Multi-Mission Platform (500 kg class spacecraft). The main mission objectives are the assessment, management and monitoring of natural resources. The phase A study is planned to be finished by mid of 2006. The key component of the SAR instrument is the SAR antenna, which is designed as an elliptical parabolic reflector antenna. 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.
