摘要：

This paper describes the basic elements developed for realization of the UWB radar: generators, antennas and registrator. Generators produce UWB signals of nano- and picosecond duration, having the form of step-like function, a monopulse, a pulse in the form of sine wave single period (monocycle). Fulfillment of FCC requirements to radiation require using of filtration UWB signals spectrum, which results in distortions of the waveform. It is shown, that a filtration of a sine wave single period pulses of 0.2ns duration provides the slight distortions. Description of TEM broadband shielded horn antenna with low side and back pattern lobes is given. Registrator for reception of UWB signals and software for secondary signal processing are described.
