Antenna patterns of scanning antenna arrays excited by supper short pulses with jitter

摘要

This paper is concerned with investigations of the performance of phased antenna arrays excited by super short pulses having non ideal rectangular form as a function of the time. In many practical situations, the exiting pulses have amplitudes decreasing with the period compared to the pulse duration. Such pulses form distortion called "jitter". The pulse jitter nature is based upon the peculiarities of the pulse forming process in the generating devices. In this paper the pick and average phased array patterns corresponding to antenna elements excitation by pulses with and without jitter having various duration, amplitude and oscillation period are compared.
