Three types of electrical excitation were considered: frequency-independent, frequency-dependent, and mixed forms of electrical voltage. It was shown that the physical causes of such dependence are the conditions of coupling between the fields and processes accompanying sound radiation by location devices, as well as the presence of mechanical and electrical strengths of physical fields in transducer systems. Based on systems of differential equations, for systems with transducers having circular polarization, analytical expressions were obtained for the differential equations describing the sound fields of location systems under coupling conditions for each type of electrical excitation. Numerical experiment results are presented and analyzed. It was established that among the given coupling conditions, only those related to the formation of acoustic fields are dependent on the character of the electrical excitation of the location devices. The advantages and disadvantages of each type of electrical excitation were identified, based on their relationship to the mechanical and electrical strengths of the transducer systems. |
