  • Time varying gain amplifier for side scan sonar applications
    Patent number: 4198702
    Abstract: A time varying gain amplifier for a side scanning sonar system having a predetermined gain versus time relationship is disclosed. The gain is substantially proportional to the square of the elapsed time measured from the last sonar pulse initiating trigger signal. The amplifier in one embodiment employs a series connection of two amplifiers, each of which has a gain which varies linearly with the elapsed time.
