A system and method is disclosed for a countermeasure threat emulator. The countermeasure threat emulator is provided in a tubular housing that may be launched from a submarine or ship. The electronics of the countermeasure threat emulator include a CPU board for running software, communicating with a computer external to the tubular housing, and data recording. The computer external to the tubular housing preferably incorporates a database that includes data representative of a plurality of foreign countermeasures as well as domestic countermeasures. The data may be downloaded to the CPU board as well as updated for reprogramming of the CPU board. A digital signal processing board preferably utilizes a plurality of DSP processors for running the main software that is capable of producing a wide range of acoustic signal outputs. A neural network may be used for analyzing acoustic sounds from incoming threats for identification thereof and for subsequent notification to the CPU board for selection of a preprogrammed response. Power amplifiers and filters are provided for converting digital streams of digital signals to analog signals for transmission by a transducer stack.
