Abstract:
Digital beamforming allows to analyze the all beams simultaneously. The implementation of digital signal processing for this challenge we used the FPGA, because the FPGAs can proceed parallel processing. We have created the 8 beams and 3 modes for 3D OFDM Radar. The mode names are Normal, Offset and Mono, which are used for different Radar applications. For DBF (Digital Beam Formation) we have used 4 antennas and each of that has 5 rectangular patch elements. The type of feeding for these antennas is serial. To achieve better side lobe level the rectangular patch sizes are modified by Dolph-Chebishev function. The receiver antenna array beam-width in azimuth plane is 25° and in elevation plane is 60°.
