众所周知,目前,在反射地震处理中所使用的各种震源(炳烷——氧气的爆炸,压缩空气的释放,炸药,水泡,机械冲击及连续震动等)在输入到地震反射系统时产生不同的压力波前。我们也都知道在以后的地震资料处理中时变滤波器的选择是一个很大的问题。选择通常是视觉的或由辅助机器决定,目的是保持时间分辨力和信噪比之诸因素间的良好平衡。由于这两种因素,则对同地区不同时间(即,用不同的仪器或不同的观测系统)所
It is well known that at present, the various sources used in reflection seismic processing (such as explosion of Bing-Oxygen, release of compressed air, explosives, blisters, mechanical shock and continuous vibration, etc.) produce different Pressure wavefront. We also know that the choice of time-varying filters in future seismic data processing is a big issue. The choice is usually either visual or assisted by the machine in order to maintain a good balance between the factors of temporal resolution and signal-to-noise ratio. Due to these two factors, different times (ie different instruments or different observing systems)
