双波段雷达和两面阵天线相结合，可应用于机载预警雷达。针对机载预警雷达的目标跟踪问题，在双波段数据融合的基础上，分析了高、低精度通道和双波段串行合并式的滤波误差，并导出了测量噪声方差和滤波迭代次数对跟踪性能的影响，然后从两个波段的配置和总滤波迭代次数两个方面，给出了两面阵双波段雷达数据处理系统的设计原则。蒙特卡洛仿真实验的结果与理论分析结果高度吻合，由此可知，根据理论分析设计的数据处理系统是有效的。

Combined with two-face antenna array,the dual-band radar can be applied in airborne early warning radar.Considering target tracking of airborne early warning radar,on the basis of dual-band data fu-sion,the filtering errors in high accuracy channel,low accuracy channel and dual-band serial combination channel is deduced,the effect of measurement noise variance and iterative times of filter on tracking perform-ance is analyzed.Then,from two aspects-configuration of two bands and total iterative times of filter,the design flow of data processing system of two-face and dual-band radar is given.The Monte Carlo simulation results are consistent with theoretical analysis results.
