Subsurface imaging can be done by using bandlimited wavelet of the seismic method. Subsurface imaging section must consider curved and dipped reflector. In otherwise, NMO/DMO method is not appropriate because of the reflector is iluminated as a point.<p> <br /> <br /> <br /> <br /> <br /> <br /> <br /> To solve the problem, that assumption is not precise anymore. In fact, reflection zone can be illuminated as a line or area, these so-called fresnel zone. Fresnel zone is the first idea of CRS's concept. by this means, the reflection of the ZO point along fresnel zone can be used to obtain stacked surface of each ZO points.<p> <br /> <br /> <br /> <br /> <br /> <br /> <br /> The aim of this study is to find data gather using conventional dan CRS methods. Subsequentely, Pre stack time migration of the conventional and CRS methods are analized. CRS's PSTM results a more focus data, more continuous event, optimum signal to noise ratio and put the reflector to the right place with less noise compared to conventional mehods.
