ABSTRACT:
A buoyant cable system and method is provided with a flexible towed platform that may be deployed into the water from a submerged submarine. The flexible towed platform has a memory that returns to a selected shape after deployment. A presently preferred selected shape may have one or more curves that provide a function during towing. For instance, in one embodiment two oppositely extending curves each float and each are pressed by the water in a balanced manner to provide a stable platform for one or more antennas which can be of different types suitable for a wide band of radio frequency reception/transmission. In another embodiment, a keel may be formed from a weighted curved portion that is suitable for vertically supporting an antenna. The flexible towed material may be constructed of coil springs, shaped memory alloys, and the like.
