Patent ID: 8786277

Claim:
A magnetic signal noise reduction and detection system, comprising: an input configured to receive data from a first total field scalar magnetometer; an input configured to receive data from a vector magnetometer; an input configured to receive data from a position, velocity and heading sensor; a signal processor configured with a pre-processor system, an adaptive noise cancellation system and a detection system, the pre-processor system configured to carry out initial processing of data received from the first total field scalar magnetometer, the vector magnetometer and the position, velocity and heading sensor; the pre-processor configured to convert data derived from the first total field scalar magnetometer, the vector magnetometer and the position, velocity and heading sensor to the frequency domain and pass the converted data to the adaptive noise cancellation system; the adaptive noise cancellation system configured to carry out multivariate regression on the converted data in order to reduce detected noise; and the detection system configured to detect magnetic anomalies and output information in real time about the magnetic anomalies to a user interface.
