摘　　要：高频毫米波雷达印制电路板(PCB)天线方焊盘矩阵精度(EA)决定了雷达辐射效率和接收信号的质量及相位,而其EA整体受天线方焊盘内角和外角设计及加工的直接影响。对PCB毫米波雷达天线方焊盘内角与外角图形进行补偿设计和蚀刻处理,并对处理过程中的相关现象展开研究。利用不同的天线方焊盘矩阵补偿设计模型(内角与外角)与经蚀刻后形成的天线方焊盘矩阵精度数据,制定最佳天线方焊盘矩阵设计补偿方案,以期为高频毫米波雷达PCB板制作提供有力的工程EA设计指导。The accuracy(EA)of the high-frequency millimeter wave radar PCB antenna square PAD matrix directly affects the radar radiation efficiency and the quality and phase of the received signal,while its overall matrix accuracy(EA)is directly affected by the design and processing of the internal and external angles of the antenna square PAD.This article presents a study on the phenomenon of compensating and etching the inner and outer corner patterns of PCB millimeter wave radar antenna square PAD.Different antenna square PAD matrix compensation design models(inner and outer corners)are used to determine and develop the optimal antenna square PAD matrix design compensation scheme based on the accuracy data of the etched antenna square PAD matrix.Provide strong engineering EA design guidance for the production of high-frequency millimeter wave radar PCB boards.
