| 摘 要： | 本文提出一种基于压缩感知的探地雷达数据压缩采集方法,实现实时的采样数据压缩,无需采集完所有数据后再压缩,采样与压缩同时进行,从而大大减小了实时采样的存储压力.探地雷达的采样信号被压缩投影到由Mersenne Twister 算法生成随机矩阵,实现压缩.该方法实现了小计算量的实时压缩,并且硬件实现简单.本文使用half-quadric的方法求解感知压缩模型中的l1凸优化,快速实现数据重构.实验表明,本文方法能将探地雷达数据压缩把到原来的1/15,大大减小实时采样存储压力.

| Abstract: | This paper presents a novel data acquisition for ground penetrating radars(GPR) based on compressive sensing(CS) by exploiting sparseness in two dimensional FFT of B-scan data.Linear projections of the returned signal with random vectors generated by Mersenne Twister algorithm are taken as measurements.Half-quadric is used to solve l1 minimization.Using experimental GPR data,it is shown that the number of acquisition data is only the 1/15 of the number usually considered necessary. |
