Abstract. The description of work of the ionosonde/direction finder with use linear-frequency-modulated signal  is given. Results of experimental researches of features of HF propagation on lines of various extent, orientation in natural and artificial-disturbed  ionosphere are submitted and is - indignant to an with help ionosonde direction finder are presented. Offers on creation of the Russian analogue of SuperDARN system on the basis of unique tool - ionosonde-direction finder are formulated.  With this purpose it is offered to open northern and middle-latitude echelons of the receive-transmitter  stations equipped by the  ionosonde-direction finder.

 

Keywords: LFM-signal, ionosonde-radiodirection finder, scattering, waveguide, modeling.
