We present work about design and studying the receiving terminal of network ionospheric chirp sounder on the USRP platform and comparisons of the current results with the data of analog chirp sounder on the ICOM transceiver. We expanded the model of an ionospheric radio channel with the aim of interpretation of results of sounding for development of high-frequency communication by representation of pulse response characteristic of the broadband channel in the form of the sum of pulse response characteristics of narrow-band adjacent channels.

SEMINATURAL MODELING MILTIFUNCTIONAL AIRCRAFT RADAR IN DETECTION MODE
In the report approach to development and realization of semi-natural model of the onboard radar for carrying out semi-natural tests of perspective systems of a radar-location is considered. This hardware-software complex allows to replace considerable part of labor-consuming and expensive natural researches of behavior of radar-tracking systems in the conditions of a difficult interfering situation semi-natural, with the set degree of adequacy.
