摘要
针对普通相控阵雷达不能在瞬时大带宽下工作的问题,阐述了光控相控阵雷达的优点。在建立的光控相控阵发射阵列天线系统实际构成的数学模型基础上,通过对其瞬时带宽的理论分析和计算机仿真,得出了光控相控阵列的瞬时带宽与阵列配置、子阵大小及扫描角均有关的结论。
The merits of the optically phased array radar are expounded in view of the fact that a conventional phased array radar cannot operate in a large instantaneous bandwidth. Based on the practical structure of OCPAR (optically controlled phased array radar), a mathematical model of the array is built and the theoretical analysis and simulation results are presented. The conclusion that the instantaneous bandwidth of the OCPAR is determined by its configuration, subarray size and scan angle is obtained.
