Factors Influencing the Design of Long-Range Echo-Ranging Equipment.

Abstract

Advantages of echo ranging in obtaining long detection ranges are pointed out. The mutually independent equipment parameters - - frequency, transducer area,power output, and recognition differential - - are consecutively discussed; and the bases of decisions regarding the choice of these parameters presented. The parameters obtainable for the first equipment are 10-kc frequency, 10-kilowatt power, 3-ft-diameter transducer, and -23 db recognition differential, with 5-kc equipment following as soon as feasible. Conclusions are drawn regarding ranges to be anticipated with the first equipment operating under various water conditions.
