| Abstract: | In this thesis,a wideband signal source of FM noise for radar is designed.Which contains three parts-generated baseband noise,digital processing of FM nosie and signal of FM noise output.Parts of the generated baseband noise and output signal of FM noise belongs to analog circuits,part of the digital processing FM noise is realized on the FPGA logic resources.The test result indicates that the design of the FM noise signal source accords with the system requirements at the present stage of research,and meet project requirements targets. |
