Abstract: Methods and systems for developing a prototype pulse in real-time. A method includes detecting, by a signal processor, a plurality of repetitive pulse signals carried in energy waves received at an antenna. The method further includes estimating time intervals corresponding to occurrences of the plurality of repetitive pulse signals and extracting a plurality of pulse signal segments detected by the signal processor during each of the time intervals over a time period. The signal processor selects a first pulse signal segment received during one of the time intervals and calculates respective time delays relative to the first pulse signal segment for each remaining pulse signal segment of the plurality of pulse signal segments. The signal processor then time-aligns the extracted pulse signal segments with the first pulse signal segment and averages the pulse signal segments to establish a prototype pulse signal.
