In this paper, general results for ideal UWB (Ultrawideband) impulse beampattern are given. It can be easily shown that the mainlobe width is similar to the narrowband case. In contrast, the absence of grating lobes and the appearance of a fixed sidelobe level dependent only on the number of antennas and not on their spacing is a beneficial property. A(More)
Beamforming for UWB signals has some special properties that are different from the narrowband case. The investigation of ideal time-delay beamforming for short pulses shows a striking feature, namely the absence of grating lobes in the beampattern. This means that the spacing of the array elements is not limited by half of the wavelength, hence high(More)
