In this case the pulse is about 950 microseconds wide, with a 1900 microsecond pulse repetition interval, giving the fairly typical (for CODAR) 50% duty cycle.)

- 06:19, 27 December 2014 Token (Talk | contribs) uploaded "File:29B6.mp3" (Russian 29B6 radar. First 22 seconds of the recording uses an audio bandpass wide enough to capture the entire swept width. Remainder of the recording at more "normal" receiver passband widths, as might be heard by most listeners.)
