A new combined Surface Acoustic Wave (SAW) convolver, or a serial searching code acquisition scheme for direct sequence spreading spectrum (DSSS) communication system is presented.
提出了一种用于直接扩频通信系统（DSSS）快速捕获，新型组合声表子波（SAW）卷积器序列搜索码捕获方案。
Wave field continuation can remove much of the energy which propagates along the surface, such as direct waves, ground roll and some random noises.
把波场沿深度外推可以消除与地表有关的“噪音” ，如直达波、面波、声波及在表层传播的随机噪音。
The debris falling back to earth may generate additional direct and surface-wave noise.
碎石落回地面可产生附加的直达波和面波噪声。
