摘要
速率陀螺敏感于天线空间运动角速率,故可将陀螺感受的角速率信息作为反馈信息构成负反馈回路,通过加入船摇扰动前馈补偿环节,实现稳定回路的复合控制。再通过误差校正后将船摇补偿输出到功放,驱动天线方位及俯仰运动,达到隔离船摇扰动对天线指向影响的目的。设计已成功应用于舰载测量雷达的研制中,经对雷达性能测试,船摇隔离度达到50 dB。
The rate gyroscope is sensitive to antenna space motion angular rate,so the angular rate information got by gyroscope can be taken as feedback information to constitute a negative feedback network.By adding the ship-swaying disturbance feedforward compensation,the compound control of stable loop is achieved.Through error correction,the compensation is output to the amplifier to drive the antenna azimuth and elevation motion,and to isolate the ship motion disturbance effects on the antenna pointing.This design has been successfully applied to the development of a kind of shipborne measurement radar.the performance test results of this radar shows that the ship rocking isolation is up to 50 dB.
