BACKGROUND

Marconi UDI (UDI), a GEC-Marconi company at the time of the WTEC team's visit, may have technical and manufacturing depth gained from its parent company.

RESEARCH AND DEVELOPMENT ACTIVITIES

The Sonavision 4000 high definition sonar system incorporates a new composite transducer array and digital processing that has closed considerably the gap between underwater television pictures and previous sonar systems. The interpretive qualities of the unit are defined by the target's shape, size, color or shade variation, and shadows. This permits the operator to more effectively identify targets. Some of the system's unique features including the following:

The composite array is the result of UDI's newly developed technology. The results are wider bandwidth and much greater efficiency in the conversion of electrical energy into mechanical energy.
