Analysis on Application of Accumulative Detection in Optoelectronic Equipment

Some optoelectronic detection equipment are required to have high detection probability and low false alarm probability. Single detection method can not satisfy these requirements, but accumulative detection method can do. Based on the analysis on application of accumulative detection in optoelectronic systems, the mathematic models are founded, and the formulae of detection probability and false alarm probability are derived. The calculated results presented indicate that the model of discontinuous K out of N used in active detection equipment can effectively improve detection probability and reduce false alarm probability, but in passive detection equipment detection probability will be somewhat ameliorative, and false alarm probability will be reduced obviosly.
