In this paper, based on circuit equations, we analyze in detail the operating principles and spectrum properties of output currents of the helical passive electromagnetic pulse generator with capacitive and inductive load respectively. Finally, we demonstrate that the generator with capacitive load has a wider waveband, making it more suitable as a wideband radiation source.

In an important case of the telemetric information transmission by means of PSK signals with the frequency multiplexing, the signal dripping from the adjacent channels may be the cause of false information. As it is impossible to predict such a result with the purpose of introducing a corresponding correction, it is advisable to select the type of signal with which the penetration into the adjacent channels would be minimum. It is shown in the report that dripping effect can be minimized at the use of radio-impulses with smooth envelope as the elements of PSK consistency. The system of transients calculating is stated accurate within the phase of the signal for the signals of such a type.

The paper concerns a system for detecting cross section of an object under test. The object is located on a revolving platform and excited with ultra short pulses. The cross section is calculated on a base of matrix constituted by the signal received coherently for different angles. Phase shift between pulses is key information in those calculations.

This paper presents a circular monopole UWB antenna, which has an approximately 30 times octave bandwidth constant group delay, acceptable gain flatness and high efficiency, and introduces the primary antenna design. In this paper, the theoretical analysis, simulation by CST Microwave Studio and experiments are all conducted to further characterize the antenna in terms of the influences on its performance by varying the dimension parameters of the antenna. Also, via the experiments, this paper originally presents the idea of improving the impedance bandwidth by modifying the structure of feeding network.
