ABSTRACT:
An underwater detection system display underwater conditions on an indicator comprised of a monochrome cathode ray tube with two groups of different degrees of brightness. One group of different degrees of brightness is related to the amplitude of echo signals in such a way that degrees of brightness are in direct proportion to the amplitude of an echo signal. The other group of different degrees of brightness has another relationship with the amplitude of an echo signal.
