摘 要
基于探地雷达信号和图象的特点,提出了两种有效脉冲压缩算法。第一种方法经过学习,得出最佳权系数,从而对任意反射信号进行压缩。第二种方法无需已知发射波形,具有较好的实际效果。

Globally Optimal Multistage Vector Quantizer Design Based on Stochastic Disturbing

()

Abstract
In this paper, the algorithm of globally optimal multistage vector quantization based on stochastic disturbing (SD MSVQ) is presented. Experimental results show that not only computation and storage is significantly reduced, but also obtained a good reconstructed image at a high compress ratio.
