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

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

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.
