Claim One:
1. A system for measuring a time semblance of a formation, comprising: a transmitter, wherein the transmitter transmits energy into the formation; a plurality of sensors comprising a plurality of consecutive sensors, wherein the plurality of sensors measures energy received from the formation, wherein at least one of the plurality of consecutive sensors is positioned in a non-uniform axial spacing configuration, and wherein the non-uniform axial spacing configuration of the at least one of the plurality of consecutive sensors is determined, at least in part, using a time semblance algorithm, wherein the time semblance algorithm comprises determining TS sum ⁡ ( s j , t ) = ( ∑ i ⁢ ⁢ A ⁡ ( s j , z i , t ) ) 2 ∑ i ⁢ ⁢ ( A ⁡ ( s j , z i , t ) ) 2 × N , wherein t is a time, wherein N is a total number of the plurality of sensors, Ns is a total number of slowness values, i is a value from 1 to N, j is a value from 1 to Ns, z i denotes a position of sensor i along a tool, s j represents a slowness value of a waveform in the formation, and A(s j ,z i ,t) represents a progression of the waveform for a particular slowness s j ; and a data processing unit including at least one time semblance algorithm, wherein the data processing unit receives measurements from the plurality of sensors and processes the measurements to determine a time semblance of the formation.
