Method and device for increasing the probability of validity detection of the reply codes in secondary radar systems

摘要

The invention relates to a method and a device for real-time processing of responses consisting of pulsed signals transmitted by secondary radar transponders. The device includes an analyser (300) of sampled parameters characterising the pulses, parameters derived by a device situated upstream of the invention. This device (300) creates a message at the sampling rate known as sample message, characterising the variations in the different parameters from one sample to another. A device (350) for processing the pulses receives the sample messages and derives messages known as pulse messages. Finally a device (380) filters the pulses belonging to the same response on the basis of the pulse message information and of response detection signals. IMAGE
