Novel methods for monopulse direction finding for linear frequency modulation based frequency diverse array (LFM-FDA) are introduced and experimental results are presented. Amplitude comparison monopulse technique constitutes a part of these methods. Radar operation is continuous wave (CW); in order to apply amplitude comparison monopulse technique on LFM-FDA, specific customizations are suggested, such as null tracking. One of the monopulse direction finding methods is implemented on an LFM-FDA setup. Results show that +/- 2 degrees direction accuracy for approximately 20 degrees beamwidth is obtained for 60 degrees azimuthal angular coverage in anechoic chamber.
