ABSTRACT:
Swimmers are detected in a given body of water by dispersing sensors throughout the water column. The sensors adhere to the swimmer and reflect acoustic energy. Acoustic energy is broadcast in the water and the swimmer is detected by the characteristic motion of the sensors clinging to the swimmer as detected by acoustic monitors. The sensors may also fluoresce and be detectible by optical monitors when a portion of the swimmer is above the water.
