Annotation
Tomography schemes based on nonlinear effects of the third order and using two coded and one monochromatic signals or three coded signals as primary ones have been compared. The algorithm of obtaining the tomogram of an acoustic nonlinear scatterer has been adapted for the scheme with three coded primary signals, and the first experiments on the modified plant have been made.
