ABSTRACT:
A multipoint reflective target system for use as sonar targets. The system ncludes a plurality of small spaced apart reflectors that are interconnected by an elongated flexible tether. The tethered reflectors are then towed in the ocean and form an elongated multipoint reflective target comprising a string of spaced apart reflectors moving under and about parallel to the ocean surface. This target is sonified by a sonar pulse and generates a reflected signal having a predetermined shape. The shape of the reflected signal is determined by a selection of parameters such as the length of sonar pulse, the spacing of the reflectors and the size and material of the reflectors. By properly selecting these parameters it is possible for the multipoint reflective target system to resemble much larger actual or similated targets.
