Navy divers face ever increasing risk of encountering diver detection sonar systems during missions. With the growing commercial market of diver detection systems there exists a need for portable devices that alert a diver to the presence of high frequency or ultrasonic acoustic transmissions in the vicinity of operation. A unique diver interface to such system must be developed to support the diver operations. To make the system effective, bearing and frequency estimates of the acoustic transmission are provided under a variety of operational scenarios. Both visual and audible warnings provided to the diver will enable real-time adjustments in routes to mitigate the vulnerability risk. Our innovative hand-held receiver packaging approach provides the ability to monitor the system without adding significant hardware to the diver. The operator interface features an intuitive solution that function under extreme in-water situations. Signal Processing must achieve high sensitivity with low false alarm rates, therefore full spectrum; spectral redundant based signal processing techniques need to be considered to enhance detection and bearing estimates within limited space/weight/volume allocations. Progeny’s understanding of the acoustic intercept problem is critical to developing a low false alarm solution to this problem.
