Research Institution

In this proposal ISL is advancing the development of a multi-sensor sonobuoy (MSS), containing acoustic, electric (E) field and magnetic (B) field sensors, which will achieve detection ranges that exceed passive acoustics. The MSS system design utilizes a horizontal line array (HLA), which provides a stable platform for long aperture E-field measurements, which consist of two types: a ULF- capable sensor and an ELF-tuned sensor. The 200 foot HLA will allow for the E-field to exceed passive acoustic detection ranges. The HLA will also provide a stable platform for highly accurate B-field measurements. Algorithmic tasks in the program will develop tools that remove noise from the E and B sensors by removing motion noise and correlated ionospheric multi-platform noise. We will also develop data fusion algorithms that combine acoustic, E and B data and will optimize detection ranges, classification and target localization. The Phase 2 will culminate in a sea-test of the MSS deployment, operation and detection capabilities. The overall program will ultimately culminate in an A-size MSS which will be air-droppable, and open to use by the Navy for ASW intelligence and tactical operations.
