Abstract:

The patent concerns an echo-ranging homing torpedo having mean for normally transmitting search pulses at a predetermined repetition rate, and having a receiver wherein detection of target echo signals, during listening intervals between search pulse transmission instants, is limited by the pressure of reverberation signals, said receiver including a TVG amplifier followed by a signal amplitude-threshold type of detection circuit for discrimination of target echo signals from said reverberation signals, the gain-increase characteristic of said TVG amplifier normally being set to limit target-echo detection sensitivity to an extent preventing false-alarm response under the maximum reverberation conditions.
