为高效利用孔径面积,着眼于复合探测系统的集成化发展,提高对重要目标的连续跟踪和精准识别能力,提出了一种雷达光学一体化集成毫米波阵列,并基于光干涉成像系统和毫米波阵列的设计参数分析了其对阵列特性的影响。设计参数主要包括透镜直径、最长基线长度、干涉基线数、阵元间距和阵列规模。仿真结果表明随着透镜直径、最长基线长度和干涉基线数的增加,毫米波阵列特性出现了不同程度的恶化。随着毫米波阵列的阵元间距和阵列规模的增加,毫米波阵列第一旁瓣电平能得到有效的改善。 |

Abstract: |
In order to utilize the area of aperture effectively, focus on the integrated development of the composite detection system, and improve the capability of continuous tracking and accurate identification of important targets, a millimeter wave antenna array for integrated radar and optics is proposed. The effect of the design parameters of the optical interferometric imaging system and the millimeter wave array on the characteristics of millimeter wave antenna array is analyzed. The design parameters of optical interferometric imaging include the lens diameter, the maximum baseline length, the number of interferometric baselines, the array element spacing and the array size. The simulation results show that with the increase of the lens diameter, the maximum baseline length, the number of interferometric baselines, the characteristics of the millimeter wave antenna array have deteriorated to various degrees. With the increase of the element spacing and array size, the first sidelobe level of the millimeter wave array can be improved effectively. |
