Further , analyse the characteristic of the seismic wavefield of fractural reservoir and the influence caused by fracture density , property of the filled material and the strike of fracture . fifthly , in term of research of zhangshulun et al . , concisely discuss the arithmetic of the plane wave forward modeling and migration with phase shift method , in prestack common offset gathers and check the arithmetic by numerical simulation
第四，用基于弹性?声学近似的反射系数计算公式和本文提出的付氏变换子波生成法得到缝洞模型的反射系数模型和子波模型并用vrselrf波场延拓算子对其进行地震波场数值模拟；进一步分析了缝洞储层的地震波场特征及缝洞密度、充填物性质和裂缝走向对其波场特征的影响。
The high entropy of the real and imaginary parts of sar raw data makes lossless - coding compression techniques unfit for sar raw data . in chapter 4 , some compression algorithms for sar raw data compression , such as baq , upq , bavq and wt - subbandcade are analyzed and discussed . an improved unrestricted polar quantizer ( upq ) , which can enhance the performance of the quantizer is put forward
第四章分别对块自适应量化( baq )算法、非约束式极坐标量化( upq )算法、块自适应矢量量化( bavq )算法和小波变换子带编码算法进行了分析和研究，并详细讨论了这些算法在工程实际中的应用。
