Abstract
There is not generally reported that a mirror image is considered as an enigmatic and a rare phenomenon which are formed between two strong reflectors or reflective targets. The mirror image is formed an apparent image below a reflector. In this report, the mirror image multiples caused between buried pipes and geological reflector are introduced using records of the stepped CW GPR exploration. The nature of the mirror image was inspected and appropriately conformed from the travel time of the reflection.
