METHOD TO DETERMINE CHARACTERISTICS OF FREQUENCY DISPERSION AND MULTIDIMENSIONALITY OF VECTOR HIGH-FREQUENCY CHANNEL IN CLARITY BAND OF IONOSPHERE COMMUNICATION LINE USING LFM SIGNALS Russian patent published in 2013 - IPC H04B7/24 

FIELD: radio engineering, communication.

SUBSTANCE: in a clarity band of an ionosphere communication line a characteristic of frequency dispersion and multidimensionality of channel elements is produced by assessment of probing signal elements compressed in a frequency domain. For probing of a vector high-frequency channel an ultrabroadband LFM signal is used; all scalar HF channels are probed simultaneously; multidimensionality of scalar channels is assessed, as well as a dispersion characteristic of an ultrabroadband vector channel in the form of a polynomial function that determines the frequency dispersion in it. Getting a continuous dependence of a delay in a multidimensional system track provides for definition of a dispersion characteristic of a vector channel in a clarity band of an ionosphere line of HF communication.

EFFECT: simultaneous assessment of frequency dispersion and multidimensionality of a vector ultrabroadband HF radio channel.
