WebOn each ship, a Chirpsounder receiver automatically synchronizes and demodulates the transmitted Chirp™ waveform by tuning the receiver in synchronization with the transmitted signal. The... An 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 and further developed in the late 1920s by a number of prominent physicists, including Edward Victor Appleton. The term … See more An ionosonde consists of: • A high frequency (HF) radio transmitter, automatically tunable over a wide range. Typically the frequency coverage is 0.5–23 MHz or 1–40 MHz, though normally sweeps are … See more An ionogram is a display of the data produced by an ionosonde; technically speaking one may call the data used to make the display as the ionogram but often this is simply implied. It is a graph of the virtual height of the ionosphere plotted against frequency. … See more • Davies, Kenneth (1990). Ionospheric Radio. IEE Electromagnetic Waves Series #31.
