Abstract


The principle of Digital Beam Forming (DBF) and Channels Equalization in External Illuminators based Radar System is briefly introduced in this paper. With the radar signal processing system debugging in outfield, the DBF performance, which is affected by channels equalization, is mainly analyzed so as to raise an available method of channels equalization. Then, associated with the design method of real-time signal processing system, realization of DBF with general signal processing platform, in which implements quickly transmiting beam datas along FPDP (Front Panel Data Port) bus, is mainly discussed. Adaptive Antenna Side-lobe Cancellation technique is used to restrain direct wave and multi-path clutter in External Illuminators based Radar System, the principle of which is analyzed later. Finally, a hardware design scheme and software realization flow scheme with general signal processing platform is given in real-time signal processing system.
