摘要
介绍了雷达上噪声干扰的一种宽带调频噪声信号源的设计。主要由基带噪声产生,噪声调制数字处理和噪声调制信号输出三部分组成。其中基带噪声产生和噪声调制信号输出部分属于模拟电路,噪声调制数字处理部分是由FPGA逻辑资源实现。测试结果表明,该方案设计的调频噪声信号源满足系统现阶段的研究要求,并达到项目要求的指标。
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.
