| Abstract: | We present a review of materials related to a chirp ionosonde and its application in the ionospheric research. The principle of operation of an ionosonde radiating a continuous signal with linear frequency modulation is described. The chirp-ionosonde resolution and gain in the signal-to-noise ratio are estimated. Examples of applying a chirp ionosonde to problems of ionospheric HF-wave propagation are considered. Prospects for ionospheric research on the basis of a network of oblique chirp-sounding paths are discussed. |
