摘　　要：机载雷达天线座常为三轴和两轴的结构型式,两轴雷达能保证天线波束法线指向目标,但载机姿态变化引起波束的滚动不能消除。在要求雷达测量精度高和波束极化方向不随载机发生变化的情况下,须采用三轴天线座的结构型式。文中针对几种典型结构形式的三轴雷达的空域稳定作出分析,并对结构型式为方位-俯仰-横滚(依次为外、中、内环)的三轴雷达作详细论述,推导了波束滚动的补偿值。The structures of airborne radar antenna pedestal usually are 2-axes or 3-axes types. 2-axes type can make antenna beam axis to point at target but can not eliminate the beam rolling caused by maneuvering of carrier aircraft. When high accuracy of radar measurement is required and for the polarization of antenna beam not changing with aspect of carrier aircraft, the 3-axes antenna pedestal must be used. This paper analyzes with the airspace stabilization problem of airborne radar for typical 3-axes antenna pedestals. In particular, it studies the airspace stabilization of radar with structures of azimuth-pitching-rolling（ outside-middle-inner ring） form and derives the compensation value of beam rolling.
