Excision CFAR BI detector in randomly arriving impulse interference

In this paper, excision (EXC) CFAR and EXC CFAR BI (binary integration) detectors in presence of randomly arriving impulse interference with binomial distributed flow and Raleigh amplitude distribution are studied. The mathematical expressions for calculating of the probability of detection and probability of false alarm in binomial distributed impulse interference are obtained. The average decision threshold (ADT) of the EXC CFAR detector is also obtained. The analytical results of the research EXC CFAR detector for binominal distribution impulse interference are more general and include the probability characteristics and average decision threshold of this detector in presence of Poisson distribution impulse interference. The obtained analytical results of excision CFAR detectors can be used in both, radar and communications receivers.
