| 摘 要： | 分析了机载预警(AEW)雷达可能采用的横柱型和竖柱型这两种基本的共形相控阵的方向图特性，提出了其阵元的放置规律，对这两种机载侧视共形相控阵雷达的杂波进行了建模，并依此模型对这两种机载共形相控阵雷达的杂波数据进行了计算机仿真，通过杂波协方差矩阵的估计求得其空-时二维杂波谱，检验了杂波模型的准确性，所做工作将对实际的共形阵具有重要的指导意义，也为进一步研究机载共形相控阵雷达信号处理和杂波抑制的技术和方法奠定了基础。

| Abstract: | The space-time clutter model and simulation of AEW (airborne early warning) radar with conformal phased array are studied. The patterns of the two types of conformal are investigated, the principle of element placement is presented, a space-time clutter model is developed, and the characteristics of the space-time clutter are analyzed. The computer simulating of generating the space-time clutter data for a conformal phased array radar is discussed. Finally, the space-time clutter power-spectra are given by estimating the covariance matrix of space-time clutter, and the simulation result shows that the model is creditable. These results are available for further researching the space-time adaptive processing for practical conformal phased array radar. |
