Abstract EN
This paper deals with the calibration procedures of an Archimedean spiral antenna used for a stepped frequency continuous wave radar (SFCW), which works from 400 MHz to 4845 MHz.
Two procedures are investigated, one based on an error-term flow graph for the frequency signal and the second based on a reference metallic plate located at a certain distance from the ground in order to identify the phase dispersion given by the antenna.
In the second case, the received signal is passed in time domain by applying an ifft, the multiple reflections are removed and the phase variation due to the time propagation is subtracted.
After phase correction, the time domain response as well as the side lobes level is decreased.
The antenna system made up of two Archimedean spirals is employed by SFCW radar that operates with a frequency step of 35 MHz.
