Abstract: A multi-sensor system adaptively utilizes communications or data bus facilities for multi-sensor signal fusion. For each source of sensor signals, a local signal processor compares each signal against a pre-determined set of hypotheses, and generates a ranking value corresponding to each hypothesis. An adaptive interface unit then selects the highest ranking values and transmits them, together with an identification of the hypothesis to which they correspond, through the multi-sensor system communication network or data bus, to the system signal processor. The system signal processor then multiplies the ranking from the various sensors, or adds their logarithms and selects the hypothesis whose product (or logarithmic sum) is greatest. This provides for transmission of the highest ranking hypothesis, or of a selection of hypotheses, to identify the target detected by multiple snsors.
