Development and Validation of Compact All Time Imaging SAR Sensor System (CATIS)

In this paper, we propose a synthetic aperture radar (SAR) system called compact all time imaging sensor (CATIS) for small satellite. The weight of CATIS is less than 5 kg. including the controller board, signal transmission and reception board, RF modulator board, the high capacity data storage board. CATIS supports the multiple input and multiple output (MIMO) mode for the high resolution image acquisition, digital IQ modulation technique for high spectral purity, and The main features of the proposed SAR system are that the system supports multiple input and multiple output (MIMO) SAR mode for high resolution image acquisition, digital IQ modulation technique for high spectral purity. Also, this paper proposes the verification and validation result of the system by conducting the AutoSAR and airborne platform SAR test.
