The active acoustic simulation was implemented for the AN/SQS-53C Hull Mounted Sonar System using simulation models and signal generation algorithms completely implemented in software and executed on general purpose array and data processors. The software requirements are hosted by a VME-bus based system comprised entirely of commercial-off-the-shelf units featuring 60 MFLOPS/3 MIPS of processing power, over 21 Mbytes of memory, standard interfaces, a real-time multi-tasking operating system, and spare provisions for future growth. The system is a common modular design having potential for reuse in the simulation of other acoustic and non-acoustic sensors, of multiple contact/multiple sensor systems requiring relative positioning, and of many other computationally intensive software systems.
