Summary:Frequency diverse array (FDA) radar has been studied by many researchers because of the range-angle dependent beampattern and potential ability of completing multiple tasks simultaneously. However, the full-band coherent receiver architecture has the problems of complicated architecture and high hardware cost. This research aims to develop a reception architecture based on signal separation that uses fractional Fourier transformation technology to separate the echo signal from each receiving element. The proposed method can obtain a good separation effect, especially for overlapping linear frequency modulated baseband emission waveforms of the FDA. The numerical simulation is performed and the results indicate the effectiveness of the proposed method.
