Antenna array layout optimization of collaborative passive millimeter-wave imaging system

  • 摘要: 针对人体安检应用中的高分辨率实时成像需求,分析了被动毫米波成像系统中相控阵体制与综合孔径体制的关系,结合两者优势提出了一种协同体制被动毫米波成像系统.针对水平方向相控阵体制布局,利用模拟退火算法进行优化,提出采用不同孔径喇叭天线作为阵列单元的方式提升阵列性能,并对主波束效率最大化及副瓣电平最平坦两种准则下的优化结果进行比较;针对竖直方向综合孔径体制布局,设计了满足基线不缺失条件的冗余度最平均稀疏阵列布局.仿真分析结果表明优化后的阵列天线结构可满足被动成像中提升功率测量信噪比(SNR)的需求.
