| 摘 要： | 建立了机载脉冲多普勒（PD）雷达模糊回波模拟源的仿真模型，分析了其工作原理和回波的统计特性，利用先内插后抽样的方法实现了回波数据的速度模糊和频域杂波模糊。通过设置模型参数，可模拟产生多种工作环境下的雷达模糊回波数据，并可通过PCI－7200高速数字接口析板输出。

| Abstract: | An ambiguous echo simulation model is proposed for the airborne pulse Doppler radar. The working principle of the model and the statistical performance of the echo signals are discussed. The interpolating sampling algorithm is proposed to achieve the velocity ambiguity and clutter ambiguity. Different echo data corresponding to different radar working environment can be obtained by selecting the parameters, such as noise power, signal to noise ratio, clutter to noise ratio as well as clutter distribution. Moreover, these data can be output through the PCI 7200 high speed digital interface board. |
