Abstract
A method of data conversion is set forth. In this system, the amplitude of a borehole sidewall response is recorded as a data record. This includes a sinusoidal representation of an interface. Several points on the sinusoidal curve are transformed in parameter space to represent dip and strike of the interface. Multiple point transform provides quality data so that noise on the signal has reduced impact. The transform is the Hough Transform into parameter space. This can be used with BHTV to provide acoustic data representing the sidewall of the well.
