| 摘 要： | 首先介绍了常用的杂波模型，利用ZMNL对地基雷达中常见的地杂波、海杂波进行建模，并基于FPGA分别实现了地杂波、海杂波实时模拟；最后对模拟数据进行分析，给出了模拟杂波数据的概率密度和功率谱密度曲线，与理论值对比得到了与理论值吻合的结果，验证了系统的有效性和准确性，为实验室的雷达系统调试提供了逼真的杂波环境，减少了研制成本。

| Abstract: | Some radar clutter models are introduced; modeling ground and sea clutter tor ground radar is carried out by using of zero memory nonlinearity （ZMNL） transform algorithm; and real - time simulation of ground and sea clutter is implemented based on field programmable gate array （FPGA）. Through analysis of simulation results, probability density and power spectrum density curve of clutter simulation data is obtained, and the results obtained are coincident with theoretical value, therefore validity and veracity of real - time clutter simulation system are well verified. Application of clutter simulation system can provide real - like clutter environment for radar system adjustment, and system development cost can be reduced greatly. |
