  • Abstract
    This paper shows the technology and the performance of the digital wide band chirp pulse generator and processor for Pi-SAR2, and the history of its development at NEC. This chirp pulse generator and processor can generate the 150, 300 or 500MHz bandwidth chirp pulse and process the same bandwidth video signal. The offset video method is applied for this component in order to achieve small phase error, instead of I/Q video method for the conventional SAR system. Pi-SAR2 realized 0.3m resolution SAR image with the 500 MHz bandwidth using this component.
