Abstract
In the particular embodiment of the invention described herein, sonar signals in the range from 200-3600 cps. are analyzed by bandshifting selected segments of 100 cps. width to the range 300-400 cps. for analysis, and indications of signals in all of the bands are presented side-by-side on a continuous printer. in addition, the modulation envelope of the detected signal, which contains low frequency modulation components, is demodulated to provide indications of such low frequency components in a target signal.
