【摘要】：舰载雷达的探测精度对于舰艇建立清晰的海战场目标态势和为舰载武器系统提供精确的目标指示至关重要。舰载雷达精度标校是保证舰载雷达测量精度的重要手段,其目的是最大程度地消除或减小舰载雷达观测中存在的系统误差,包括标定和校准两个环节。本文重点研究舰载雷达探测精度标定的方法和设备,从根本上解决非靶场情况下,舰艇驻泊停靠码头,不动用其它兵力配合,随时进行舰载雷达精度标定的难题。本论文主要由四大部分组成。第一部分舰载雷达探测精度标定方法及总体方案研究：研究了基于存储转发的有源标定法、基于旋翼无人机的动态标定法和基于天线对称性和步进扫描的二次雷达标定方法,论证了舰载雷达标定的总体技术方案；第二部分静态标定设备及关键技术研究：基于存储转发的有源静态标定方法,设计实现了静态标定设备,给出了实现中涉及的“基于数字储频的多普勒调制技术”、“复杂体制雷达信号适配技术”和“时-空-频-能”四域综合处理技术等5项关键技术的实现方法,并对实际试验数据进行了分析；第三部分动态标定设备及关键技术研究：基于旋翼式无人机的舰载雷达动态标定方法,设计实现了动态标定设备,给出了合作目标一体化设计技术、目标回波增强设备技术和雷达测量数据实时录取技术等4项关键技术的实现方法,分析了实际测试结果；第四部分联合数据处理算法研究：研究了数据时空统一、野值剔除和数据混合补偿滤波算法等动态数据处理方法,并给出了实际处理效果。本文研究结果表明,采用动静结合的综合标定方法和研制的舰载雷达综合标定系统,解决了非靶场情况下舰载雷达无机动式标定手段问题,实现了一套系统可以标定现役所有舰载雷达,将一艘舰艇7-8部雷达的标定时间从2周缩短至2天,不再需要舰艇转场和申请飞机,极大缩短了作战准备时间,已经产生了较大的军事和经济效益。
[Abstract]:The detection accuracy of shipborne radar for ship building sea battlefield clear and provide precise target indication is of vital importance for shipborne weapon system. Shipborne radar calibration of shipborne radar is an important means to ensure the measurement accuracy, the objective is to minimize the system errors are reduced or the shipborne radar observation, including calibration and calibration two links. This paper focuses on the research of shipborne radar detection method and equipment calibration, solve the non range situation fundamentally, the ship anchored dock, not to use other forces with the problem of shipborne radar calibration at any time. This thesis consists of four parts. The detection method of calibrating accuracy and the overall plan for the first part: Study of the shipborne radar calibration method based on active storage forwarding, dynamic rotor UAV calibration method based on the antenna and to call on Two calibration methods of radar and step scan, the overall technical scheme of shipborne radar calibration demonstration; research of key equipment and technology of static calibration of second parts: the static calibration method based on active storage and forwarding, the design and implementation of static calibration equipment, gives the realization of "Doppler modulation technology" based on Digital frequency, "method of complex radar signal adaptation technology" and "space - time - frequency -" 5 key technologies of four domain comprehensive treatment technology, and the actual test data are analyzed; the research of key equipment and technology of third parts: dynamic calibration method of shipborne radar calibration dynamic rotor UAV Based on the design and implementation of dynamic calibration equipment, and gives the cooperation target integration design, echo enhancement technology and equipment of radar measurement data real-time recording technology 4 key technology The operation method, analysis of the actual test results; the fourth part combined with the data processing algorithm research: the data space uniform, outlier elimination method and hybrid compensation data filtering algorithm for dynamic data processing, and gives the actual treatment effect. The results of this study indicate that the integrated shipborne radar calibration method and the combination of static and dynamic development the comprehensive calibration system, to solve the problem of dynamic calibration method of shipborne radar range inorganic case, implement a system can calibrate all active shipborne radar, a ship 7-8 radar calibration time shortened from 2 weeks to 2 days, no longer need to apply for ships and aircraft transitions, greatly shorten the combat readiness time has produced a larger military and economic benefits.
