一种窄波束测控装备车船摇隔离方法

A method of vehicle/ship swing isolation for narrow beam TT&C equipment

针对车载/船载状态下的窄波束测控装备的“动中测”测控需求,提出一种“位置环+车船摇前馈补偿+陀螺稳定环”的车船摇隔离方法,并对该方法的船摇隔离度和车摇隔离度分别进行仿真分析,仿真结果表明,采用该方法时,船摇隔离度能达到50 dB以上,车摇隔离度能达到20 dB以上;利用该方法对船摇条件下的高速运动目标跟踪性能进行仿真,仿真结果表明,跟踪误差满足窄波束测控装备的跟踪要求。

To meet the requirements of“measurement in motion”for narrow beam TT&C equipment in the vehicle/ship state,a method of“tracking loop&feed-forward compensation of ship swing&gyro stabilization loop”for vehicle/ship swing isolation is proposed.Through simulation and annalysis the ship swing isolation and vehicle swing isolaiton,the simulation results show that with this method,the ship swing isolation can reach above 50 dB and the vehicle swing isolation can reach above 20 dB;The method is used to simulate and analyze the tracking performance of high-speed moving targets under the conditon of ship swing,the simulation results show that the tracking error meets the tracking requirements of narrow beam TT&C equipment.
