  • Patent number: 10240970
    Abstract: Systems and methods for maritime infrasound detection can include at least one waterborne platform. A microbarometer, inertial measurement unit (IMU) and heave cancellation component (HCC) can be mounted on the waterborne platform. The HCC can receive a pressure input from the microbarometer and the IMU to generate an output pressure that can be indicative of an infrasound signal of interest (SOI). The HCC can further include a filter and an adaptive algorithm. The filter can receive IMU pressure and environment noise pressure as inputs. An error signal from the HCC output can also be supplied through a closed feedback loop that includes a Recursive Least Squares adaptive algorithm, which can further include a weighted, tapped delay line. The system can further include a remote data center for receiving the HCC output from the waterborne platform(s), which can be buoys, vessel or USV's.
