摘　　要：随着高频段(X频段乃至Ka频段)天线在航天测控中的不断应用,由于波束非常窄,对捕获跟踪低轨的高动态目标,这将是一个新的技术难点,而在远望号测量船上,加之船摇的影响,窄波束捕获跟踪问题将更加突出;如果船摇隔离度不够,会导致船摇残差过大而导致目标丢失,为了提高跟踪精度,一般采用中心机前馈或陀螺前馈进行速度补偿,等效于提高了系统的加速度误差常数(Ka值);与中心机前馈相比,陀螺前馈在测量精度、实时性方面存在优势,在船载雷达伺服系统中得到推广应用;文章主要讨论前馈陀螺的两种安装形式、转换公式以及在船载雷达伺服系统中的应用效果。When high frequency is applied in space TT＆C, such as X--band and Ka--band, the beam angles of ladar antenna become narrower and narrower, So it is a new technological difficulty to catch and track the low--orbit and high--dynamic objects, especially on the instrumentation ship. Lower ship--swing isolation can cause bigger ship--swing residual and at last the tracking object is lost. At present, the feed--forward from center computer system and the feed--forward gyroscope are separately adopted to increase the acceleration error coefficient, i. e. the Ka Value, of shipborne radar servo system, and the latter is superior in precision and real--time. This paper mainly discusses two kinds of installing forms, conversion formulas and application effect about feed--forward gyroscope.
