Abstract
The model previously developed for calculating the characteristics of elastic waves emitted by a laminar direct-acting transducer is used to calculate echo signals for combined or separate similar transducers. The calculation was done in the asymptotic approximation (of ray acous tics) in the emission-reception far zone. Examples of the calculation of the relative emf on the receiving transducer are given.
