ABSTRACT:
A resolving power target for side-scanning sonars and other sound transming devices such as but not limited to ultrasonic devices. The target is a planar sheet having one smooth surface to which a resolution pattern is masked. An adhesive is applied to the masked pattern and articles such as gravel or other three-dimensional equivalents are introduced to produce the irregularity to the smooth surface within the confines of the resolution pattern. The resolution pattern for a particular application is selected experimentally, however, a Limansky pattern is used in the present invention for side-scanning sonar resolution measurements.
