Abstract

To compress SAR phase history data, we pro- pose two methods that arc optimized for different performance criteria. The first is a variable-rate sys- tem that uses entropy-constrained trellis-coded quantization (ECTCQ) in conjunction with adaptive arithmetic encoding. The second system is a fixed- rate design that uses channel-optimized trellis-coded quantization (COTCQ) designed for the binary sym- metric channel.
