Principles of creation of ultra- wideband systems for transmission information on the base of ultrashort radiopulses. Questions of energetic characteristics and scheme realization are investigated.
The model of growth of a fatigue crack in conditions of dynamic compression has been developed. Features of fatigue cracks nucleation and development in steels with various structure have been revealed. It has been found out that preferable directions of crack development are the grain borders or boundary surface between structural components. Nonmetallic inclusions are places of primary microcrack...
Propagation features of ultrashort microwave pulses in the passive elements of a microwave tract are studied. Investigations of ultrashort microwave pulses generator and double balanced ultra-wideband phase detector are carried out. Optimal parameters of the communication system elements on the criteria of the minimal distortion of ultrashort pulses are found
Possibility of creation of ultra-wideband communication systems on the base of ultrashort radiopulses is considered. Questions of energetic characteristics and system are investigated
