Calculation of the Energy Characteristics of Vertical Sonar Sensing Systems Taking into Account the Complexity of the Radiated Signal

Presents an energy calculation algorithm for three vertical sonar sensing systems: an echosounder, an ice thickness measurement system and a bottom soil profiling device, taking into account the use of a complex broadband signal as a sounding one. It is shown that as the complexity (base) of the signal increases, the level of required acoustic pressure developed by the antenna decreases. Expressions of optimal frequencies for calculations of the echosounder, ice thickness measurement system and bottom soil profiling device are determined, examples of calculations of optimal and operating frequencies for each considered sonar are given.
