Abstract:

A filtering and data fusion technique is described which uses the correlation between the two data streams of a dual-frequency sidescan sonar in order to discriminate against noise and preferentially enhance features of desired relative size. The filter is applied to data collected with a Klein 590 dual-frequency sidescan sonar with the parameters adjusted so as to enhance the display of minelike objects. Experience with the filter shows that it is highly effective in noisy conditions.
