Patent ID: 7154811

Claim:
A simulator for developing an acoustic detector of an underwater vehicle, comprising: an I/O communication unit for receiving information required for simulating an underwater environment from an acoustic detector and a motion simulator; a signal generator for receiving the information from the I/O communication unit to calculate a digital signal model; a DA converter for converting the digital signal model into an analog signal; a signal conditioner for generating a signal similar to the signal of an actual underwater environment by controlling frequency and gain of the analog signal; and a remotely controlled computer for loading an OS to the signal generator and displaying various operation status; wherein the signal generator comprises: a central controller for receiving the information and controlling operations of the simulator; and a plurality of processor units for calculating and generating the digital signal model for each channel according to a command of the central controller, wherein the central controller and the plurality of processor units are connected in a process farm structure so that a signal model among channels has parallelism.
