Detection of Targets in Three Simulated Sonar Presentation Modes.
Abstract
Target detection performance was compared across three simulated sonar presentation modes: single channel binaural, four channel binaural, and eight channel dichotic detection. The multi-channel tasks simulated the 'search' modes of the AQS-13 and AQS-13B sonars respectively. The results showed a 3.4 dB decrement in performance for the four channel task and a 4.1 dB decrement in performance for the eight channel task compared to the single channel task. Almost half the decrement in performance was due simply to the presence of the additional bands of noise, the other half to the requirement that more than one channel be monitored at a time. One possible way to improve target acquisition would be to present the channels successively on successive pings. (Author)
