Abstract:
In a sonar communication system, a transceiver for receiving doppler signals, a local oscillator for producing a first output signal of given frequency, a translation resolver connected to said local oscillator for a regulating said first output signal, modulator connected to said transceiver resolver for mixing said received doppler signals and said regulated first output signal, a filter coupled to said modular for filtering said mixed signals, a precision clock oscillator adapted for producing a second output signal, a proportional resolver electrically coupled to said precision clock oscillator for regulating the frequency of said second output signal, a signal generator connected to said proportional resolver and driven by said regulated second output signal for generating a third output signal, a filter coupled to said signal generator for filtering said third output signal, a correlator electrically coupled to the outputs of said mixed signal filter and said third output signal filter for correlation thereof, a drive motor, means connected to said drive motor for regulating the speed and rotation thereof, and gear means interconnecting said drive motor and said translation and proportional resolvers for driving same at a predetermined speed ratio.
