Theoretical normalized coherence functions for a narrowband sinusoidally varying target. As the transmit beam is laterally translated by x0 to form an SLSC image, the coherence function at each value of x0 is a sum of multiple triangle functions. N is the number of transducer elements in the transmit aperture. Lag refers to the spacing between transducer elements.
