Enhanced monopulse radar tracking using fractional Fourier filtering in the presence of interference [PDF]
, 2010 Monopulse radars are used to track a target that appears in the look direction beam width. Significant distortion is produced when manmade high power interference (jamming) is introduced to the radar processor through the radar antenna main lobe (main ...
