Abstract
Both signal amplitude presentation and noise suppression presentation of sonar signals have been known for some time, but have been incompatible in the same display system. In this disclosure, means are provided for separately processing the received signal in two parallel paths, one through a noise-pulse suppression processor, and the other through a signal amplitude differentiation processor which adds an additional adjustable time delay so that the signals processed through both paths are initiated at the same time and thus can be presented together.
