Quantum Mechanical Approach to Modeling Reliability of Sensor Reports

Dempster-Shafer (D-S) evidence theory is widely applied in multi-sensor data fusion. However, lots of uncertainty and interference exist in practical situations, especially on the battlefield. It is still an open issue to model the reliability of sensor reports. Many existing methods are proposed based on the relationship among collected data. In this letter, we proposed a quantum mechanical approach to evaluate the reliability of sensor reports, which is based on the properties of a sensor itself. The proposed method is used to modify the combining of evidences. A numerical example is used to show the effectiveness and efficiency of our method.
