| 摘 要： | 采用概率统计计算中的反变换法和接受-拒绝法研究生成了幅度上服从瑞利分布、韦伯尔分布、莱斯分布、K分布和对数正态分布的非正态杂波基带调制数据,通过希尔伯特变换,生成I、Q随机数序列,并用MATLAB进行仿真。利用FPGA等实时产生出的雷达杂波基带I、Q随机数序列,经过数字正交上变频器即可产生出雷达杂波中频模拟干扰信号。

| Abstract: | The inverse-transformation method and the reject io n method in computational methods of probabilistic statistics to produce I,Q clu tter base-band modulation data are proposed.The amplitude probability density d istribution of these data obeys Rayleigh,Weibull,Rice,K or Lognormal distributio ns.In addition,I,Q random sequences are produced by Hilbert transforms,and then simulation with MATLAB is given.Base-band I,Q random data of radar clutter can be produced in real-time by using FPGA,and intermediate-frequency analogue int erference signals of radar clutter can be produced by DUC. |
