倾角滤波器是一个精确的频率-空间域偏移所必需的,因此,可靠和高效的滤波器设计和应用在理论上及实际上都是同等重要的。频率-空间域倾角滤波器通过使用Butterworth和Chebyshev运算法则来实现。把滤波器转换函数的乘积项转换为计算求和,一个串接(一系列)的Butterworth和Chebyshev倾角滤波器能够并行以提高效率。对于一个给定阶次的滤波器的,Butterworth和Chebyshev滤波器的成本是相同的。然而,Chebyshev滤波器具有一个比相同阶次的Butterworth滤波器狭窄的过渡带,但是在一些以波数-依赖的振幅波动为代价下,使它对于相位补偿比Butterworth滤波器有更高的效率。对于耗散能量的消除和对于分割误差的相位补偿,两种实现的方法已经被3D单向的频率-空间深度域偏移合并在了一起;一个单一的滤波器完成了两个目标。
Tilt filters are necessary for accurate frequency-space domain offset, so reliable and efficient filter design and applications are both equally important in theory and in practice. Frequency-space domain dip filters are implemented using Butterworth and Chebyshev algorithms. Converting the products of the product of the filter transfer functions into a calculated sum, a cascade (a series of) Butterworth and Chebyshev dip filters can be run in parallel to improve efficiency. The cost of Butterworth and Chebyshev filters is the same for a given order of filters. However, the Chebyshev filter has a narrower transition band than a Butterworth filter of the same order, but at some cost to phase-compensate more efficient than a Butterworth filter at some wave-magnitude-dependent amplitude fluctuations. Both dissipative energy cancellation and phase compensation for the segmentation error have been combined in two unidirectional frequency-spatial depth domain offsets; a single filter accomplishes two goals.
