A sonar system for the detection of signals reflected from a sloping ocean bed in which a sample of the transmitted signal is modified to correspond to the received signal as modified by the sea bottom before both signals are applied to a correlation detector. Modification of the transmitted signal sample is provided by summing incrementally delayed portions of the transmitted signal sample.
