Abstract:
A method for evaluating a sonar system, said sonar system comprising at least one sender and at least one receiver, said method comprising:positioning said at least one sender and said at least one receiver at a plurality of sensor depths; positioning a target at a plurality of target depths for each of said plurality of sensor depths; determining a detection range for each of said plurality of sensor depths for said at least one sender and said at least one receiver; finding a maximum detection range and a minimum detection range from said determined detection ranges; summing said detection ranges for each of said plurality of sensor depths to produce a detection range sum and dividing said detection range sum by a number representative of a number of said plurality of target depths to produce an average detection range; determining a range difference for each of said plurality of sensor depths between said maximum detection ranges and said minimum detection ranges and dividing said range difference by said maximum range to produce a scaling factor; selecting a range weighting term; and producing a performance rating for each of said plurality of sensor depths from said average detection range, said scaling factor, said minimum detection range, and said range weighting term.
