Available in PDF, EPUB and Kindle. Book excerpt: The Naval Research Laboratory (NRL) is investigating polarization features of antennas to determine if they can be used for radar identification. This report presents the results of a test under this program whose main objective was to use existing polarization measuring hardware to examine the mainlobe and sidelobe antenna polarization characteristics of different navigation radars and to evaluate how this information can be used for radar identification. A theoretical model was generated to plot the polarization characteristics of slotted waveguide arrays, the type of arrays used in navigation radars. A comparison between theory and real-time measurements was made with encouraging results. This report shows that radars belonging to the same 'class' with the same antenna polarization, can be distinguishable when comparing their mainlobe and sidelobe antenna polarization characteristics.
