DSP hardware implementation of BAVQ encoding for SAR raw data

摘要

This paper describes the available compression algorithms for SAR (synthetic aperture radar) raw data. The compression performances of three typical algorithms have been compared and the BAVQ algorithm is selected in view of the trade-off between the performance and the complexity. The hardware implementation scheme of the BAVQ encoder has been designed and the DSP hardware simulation result proves the feasibility of the DSP implementation.
