METHOD FOR DEINTERLEAVING PULSE TRAIN OF RADAR SIGNAL

摘要

The present invention relates to a method for deinterleaving a pulse train of a radar signal based on a divide and conquer method. A method for deinterleaving a pulse train of a radar signal according to an embodiment of the present invention includes the steps of: dividing a pulse train of a radar signal into a plurality of groups first on the ground of time of arrival (TOA); estimating pulse repetition interval (PRI) according to a plurality of secondly divided groups, and extracting pulse trains having the estimated PRI; calculating specification about the extracted pulse trains; merging pulse trains having a fixed PRI type among the extracted pulse trains; and merging pulse trains having a jitter PRI type among the extracted pulse trains.;COPYRIGHT KIPO 2014; [Reference numerals] (AA) START; (BB) END; (S100) Divide pulse train of radar signal into plural groups first on the ground of TOA; (S200) Divide plural groups divided first into plural groups secondly on the ground of fixed number; (S300) Estimate PRI per secondly divided plural groups, and extract pulse trains having estimated PRI; (S400) Calculate specification about extracted pulse trains; (S500) Merging pulse trains having fixed PRI type; (S600) Merging pulse trains having jitter PRI type
