Method and system for multi-sensor data fusion
First Claim
1. A method for integrating data received from a plurality of sensors, comprising:
- receiving data from a plurality of sensors;
determining a SNR (signal-to-noise ratio) for each sensor based on signal measurements of the received data; and
determining at least one reliability function for the plurality of sensors as a predetermined additive calculation of each sensor reliability function which are determined and individually weighted based on said SNR for each sensor and differences between predetermined operating characteristics for each sensor.

Abstract
A multi-sensor data fusion system and method provides adaptive weighting of the contributions from a plurality of sensors in the system using an additive calculation of a sensor reliability function for each sensor. During a predetermined tracking period, data is received from each individual sensor in the system and a sensor reliability function is determined for each sensor based on the SNR (signal-to-noise ratio) for the received data from each sensor. Each sensor reliability function is individually weighted based on the SNR for each sensor and a comparison of predetermined sensor operation characteristics for each sensor and a best performing (most reliable) sensor. Additive calculations are performed on the sensor reliability functions to produce both an absolute and a relative reliability function which provide a confidence level for the multi-sensor system relating to the correct classification (recognition) of targets and decoys.
