It was shown that a decrease in the readiness factor of an aircraft responder, as well as the probability of detecting single pulses of the used response signals in requesting radar systems for observing the airspace, leads to an increase in both the delay of the output pulses and to an increase in the magnitude of the dispersion. The method of decoding response signals with inter-period pre-processing of response signals is more preferable due to the fact that it has both a shorter delay time and a variance in the estimation of the delay time in comparison with the method of decoding with subsequent inter-period processing of the received signals.enAirspace Control SystemsAir Traffic ControlSecondary Surveillance RadarIdentification Friend or FoeAir objectArticle
