Abstract :
MOSAR is a multifrequency and multipolarization radar system used for analysis of aircraft radar cross section by means of measurements in the low VHF frequency band (20-80 MHz). At first, basic principles of this project are presented and technical choices are explained. After extraction of radar cross sections (RCS) from the MOSAR data, a target identification algorithm, based on a comparison with a numerical database containing RCS of commercial aircraft, is applied to measurements. The influence of signal to noise ratio (SNR) and flight level is evaluated.
