Modelling Time-of-Arrival Ambiguities in a Combined Acousto-Optic and Crystal Video Receiver

Abstract

The probability of pulses overlapping in time being received by a combined acousto-optic/crystal video receiver is investigated. Theoretical analysis and computer simulation results are compared for a variety of high pulse density scenarios and for two crystal video band configurations. Upper and lower bounds are derived for the probability of coincidence. It is shown that a small number of high duty cycle emitters will cause an unacceptable number of pulses in that bandwidth. The number of frequency subbands with crystal detectors required to cover the acousto-optic receiver bandwidth is therefore a compromise between cost and complexity of implementation.
