Chirp measurement
WebAn ionosonde, or chirpsounder, is a special radar for the examination of the ionosphere. The basic ionosonde technology was invented in 1925 by Gregory Breit and Merle A. Tuve [1] and further developed in the late 1920s by a number of prominent physicists, including Edward Victor Appleton. WebJul 25, 2014 · Chirp signals/signatures are encountered in many applications ranging from radar, sonar, spread spectrum, optical communication, image processing, doppler effect, motion of a pendulum, as gravitation waves, manifestation as Frequency Modulation (FM), echo location [1]etc. Mathematical Description:

Webchirp: [verb] to make a chirp or a sound resembling a chirp. WebThe target (corner reflector) is kept at a distance so that it generates an IF of around 1 MHz. The chirp parameters are chosen appropriately. A narrow-band RF sweep is chosen that sweeps in the center of the band. Narrow band is chosen to minimize the frequency-dependent beam tilt. Next, the elevation angle is swept.
Webtemporal chirp measurement techniques are either direct or indirect and they are based on the pulse response of laser diodes. The direct techniques are easier but require a fast detector and rely on a reasonable estimate of the pulse shape.
