Abstract: In this paper, hybrid monopulse phase-amplitude comparison method is presented. Design has been realized for broadband radar signals in real time in the digital environment. Multi-antenna array is used with a wide antenna pattern disposed on a plane in direction finding (DF) techniques with a traditional phase comparison method. With recommended method in the article, integrated amplitude and phase comparison method with fractured antennas' placements is used for solution of ambiguity. It is too hard to determine phase differences by using amplitude differences coming from fractured antennas's placements. This challenge is resolved by using FFT. For a particular incidence angle sector, analysis are performed with different antennas' placement scenarios and different signal to noise ratio (SNR). Successful DF estimations are accomplished with recommended fractured, two antenna structure and hybrid phase-amplitude technique.
