Paper Abstract

This paper aims to present a calibration optimization method for radar cross section measurement setup using time domain measurements. The proposed method requires a measurement of S21 parameter of a metallic plate with a known RCS at 13 different distances. A post processing technique reveals the correlations between the distances of measurements and time domain representations of S21 extracted parameter. Time-domain representation of S21 also depends on the wave propagation time on the antenna (Vivaldi and log-periodic) feeding line which inserts a delay. Time domain perspective clearly provides propagation delay data on antennas which are almost undetectable in frequency field. The principles of this method are provided together with experimental and simulation validations. At a distance of 22cm between antennas, mutual coupling influence affects every measurement set and is being reduced in post processing. This method also provides the impulse response of the whole measurement setup.
