Abstract or Summary
  • The resolution of multiple overlapped reflections is achieved by designing inverse filters using frequency domain deconvolution. A careful study reveals a number of problems involving frequency domain design of spike inverse filters. These include the presence of noise and aliasing in both the filter response and its output resulting from basic wavelets with zeros on or near the unit circle. Although Gaussian filters of much shorter length can be designed in some instances, they result in poor resolution. Higher resolution spike filters are designed using two frequency domain deconvolution methods that reduce the noise and aliasing problems while maintaining a reasonable accuracy. A comparison of the two methods for three different types of basic wavelets is also presented.
