PERFORMANCE OF REDUNDANT AND DISTRIBUTED DETECTION SYSTEMS WITH PROCESSOR FAULTS.
The authors examine the performance of signal detectors when processors can have faults. The fault tolerance of two systems, the redundant system and the distributed fusion network, are examined. The optimal fault-tolerant design for each system is presented. The performance of the fault-tolerant systems is compared to the faulty simplex processor. In the absence of processor failures, the redundant system is identical to the simplex processor. However, when failures occur, the redundant system performs better than the simplex processor. The fault-free fusion network does not perform as well as the fault-free simplex processor. However, in the cases examined, when failures occur in systems with many (N greater than 12) channels, the fusion network performs better than the simplex processor.
