Abstract:
1. A method for estimating a position of a target of interest using a plurality of position detection sensors, said method comprising: for at least one of said sensors, receiving a detection status from the sensor and obtaining a detection probability profile corresponding to the sensor, wherein said corresponding detection probability profile comprises a time-variant three-dimensional distribution defining the sensor's possible detection envelope and the computed probability of detection of the target of interest corresponding to each region of said envelope; combining each of said corresponding detection status and said detection probability profiles to generate a global detection probability profile, said combining comprising probabilistically adding a first given probability profile in the case where a first given corresponding indication comprises a target detection, and probabilistically subtracting a second given probability profile in the case where a corresponding second given indication comprises a target non-detection; and estimating said position of said target corresponding to the highest probability region(s) in the generated global detection probability profile.
