Abstract:

The patent describes a circuit for converting the output of a clipper correlator to signal-to-noise ratio in a signal from a sonar array, comprising a primary diode and a capacitor in parallel therewith, and a series of resistor-secondary diode combinations. Different resistor-secondary diode combinations approximate different regions of the output of the clipper correlator, thus giving an output representing signal-to-noise ratio of the signal. A modified form of the circuit uses field effect transistors and differential amplifiers as circuit elements.
