Picosecond ultra-wideband short pulse radiated by antenna arrays
Abstract
This report presents the experiments to study the characteristics of the picosecond ultra-wideband pulses coherent radiation. The testing involves bow-tie horn antennas for both the transmitting and receiving antenna. Sixteen channels of electrical pulses with 290 ps duration and jitter <30 ps have been used. The antenna arrays with various frames of 4 × 1, 4 × 2, 4 × 3, 4 × 4 are employed to radiate the pulses. The receiving antenna measures the electrical field in different distance from the transmitting antennas array. The results show that if the pulses are in coherent condition, the peak power pulse of output by antennas array with N elements are N2 of that of the single element antenna. © 2007 Wiley Periodicals, Inc.
