A saturated parametric acoustic receiver

An analysis is presented for a saturated parametric acoustic receiver that is based on the fact, first derived by Fenlon for low-amplitude waves [J. Acoust. Soc. Am. 51, 284–289 (1972)], that saturation loss for the sum- and difference-frequency components is essentially the same as that of the pump frequency alone. After extension of this result to high-amplitude waves, the theory of Rogers, Williams, and Barber [Nav. Res. Lab. Rep. 7484 (29 December 1972)] is then modified to account for saturation. Experimental data showing the validity of this approach are presented.
