| 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。

| 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. |
