A large absolute bandwidth of IR-UWB signal offers high resolution localization system with improved ranging accuracy. In such system, both the peak position and pulse width of the radiated pulse vary with directions, which can cause error in detecting the peak position of pulse. The range measurement of UWB localization system may be affected significantly by the angle-dependent pulse distortion...
The time sequence control scheme of exciting pulses for ultra-wideband (UWB) antenna array is investigated in consideration of the angle-dependent pulse distortion in UWB short pulse radiation. For a linear UWB antenna array with 5 rectangular aperture antennas as elements, three different time sequence control scheme, viz. the conventional initial-range delay scheme, the peak-range delay scheme,...
