  As the size of a submarine sensor array increases, the complexity of the associated power- and signal-distribution cables becomes a major issue both in terms of affordability and reliability. If the sensors in the aperture can be supplied the necessary power in a wireless fashion, and if the data collected by the sensors can be transmitted similarly without hardwiring, the deployment of large arrays will be greatly facilitated. Dr. Rajeev Bansal, working collaboratively with General Dynamics Electric Boat, is involved in a proof-of-concept study to assess the wireless operation of a waterborne sonar array. Dr. Bansal seeks to develop and design, using off-the-shelf components as much as possible, a wireless power- and signal-distribution system for use with a small number (at least four) of acoustic sensors. Ideally, system power will be supplied in the form of RF energy by a single transmitting source located in a chamber behind the sensor array; it will be received and converted to DC in a module associated with each sensor; and the data transmitted by the sensors will be picked up by a single receiving antenna for subsequent de-multiplexing.
