ALGORITHM FOR TIME SELECTION OF PULSED SEQUENCES IN A MIXED RADAR SIGNAL STREAM

Tsarik Dmitry Vladimirovich

The problem of separating pulse sequences in a mixed flow of radar signals with restructuring of the pulse repetition period is considered. An algorithm for solving this problem is proposed, which is based on the use of an integral transformation of the pulse repetition intervals as a tool for estimating the periodicity and includes three stages. At the first stage, using the method of histogram analysis, the range of change in the pulse repetition period (PRP) in the input signal is determined. Then, sequences are searched for with a constant PTR and with a change in the PTR from and pulse to pulse according to a regular law. At the final stage, the presence of a sequence with a rearrangement of the PPI, relative to the average value, according to a random law, is considered. It is noted that the proposed algorithm is focused on the selection of pulse sequences with PPI wobble from a mixed stream and can be used in radio control equipment.
