Abstract :
A multistatic network of autonomous active transmitters and receivers, such as deployable underwater surveillance systems, often provides multiple contacts of the same target. The present paper examines the effects of receiver diversity (“spatial diversity”) on a multistatic system, where three independent, spatially separated sonar receivers detect the same target, insonified by the same FM or CW pulse, and the contacts are merged together after detection
