Abstract

In this contribution, we numerically investigate if the quasi-stationary response is a valid approximation for the response of antennas excited by wideband linear-frequency modulated continuous waveforms. We give results for two idealized example systems, showing how the validity of the quasi-stationary response is dependent on the system's resonant behavior, and that the error between exact output and quasi-stationary response is approximately linearly dependent on the sweeprate of the linear-frequency modulated excitation. We then conduct our simulations for a realistic wideband radar system operating from 5 GHz to 8 GHz, and using impulse responses extracted from electromagnetic simulations of a dipole and a biconical antenna.
