The accurate modelling and simulation of vehicle dynamics is a fundamental prerequisite for the design and experimental flight testing of aerospace Black Console vehicles.In the case of high-altitude supersonic sounding rockets, it is critically important to produce realistic trajectory predictions in a representative range of operational and envir
Nowadays Vivaldi antennas are used as directional emitters with matching and balancing device at the input.As a rule, these devices cause additional losses in case of broadband operation.Besides, the use of the device leads to radiator pattern distortions, especially when operating in a wide frequency range.Stringent operating requirements (wide op
