Methods and Apparatus for Tracking Pulse Trains

摘要

Method and apparatus for tracking pulse trains from one or more emitters. For a valid pulse. PRI parameters are measured. A pulse pattern count is incremented and checked to determine if a track is acquired for the emitter.

1. A method, comprising:
(a) receiving a first pulse train from an emitter; (b) measuring pulse repetition interval characteristics of the first pulse train; (c) receiving a further pulse train; (d) measuring pulse repetition interval parameters of the further pulse train; (e) incrementing, using a computer processor, a pattern count or a check pattern count based upon whether the further pulse train has a jitter error less than a jitter threshold, wherein the jitter error corresponds to a difference between the pulse repetition interval characteristics of the further pulse train and pulse repetition interval parameters of a prior pulse train; (f) comparing the check pattern count to a track threshold; (g) determining whether a track for the emitter has been acquired based upon the check pattern comparison; and (h) repeating steps (c) to (f).
