摘要
为解决近程搜索跟踪系统对空中目标的快速锁定,分析了目标回波的特点,通过对目标回波进行的预处理,包括点迹的稳健凝集、副瓣和辅助质心的消除,提高了数据质量,减少了后续处理的工作量,为航迹快速起始奠定了基础。给出了目标航迹快速起始的2种方法:两点起始和三点起始航迹。建立的模型和采用的方法在多个工程项目中进行了应用,达到了快速起始的目的。
To address the issue of fast lock of aerial target by short-range search and tracking system,the characteristics of target echo are analyzed.Through target echo pre-processing,which includes robust plot clotting,side lobe and ancillary centroid removing,the data quality is improved,and the data quantity is decreased in further processing.On the basis of this,two methods for fast target track initiation,i.e.track initiation with two points and three points,are given.The models and methods are applied to many engineering projects,realizing fast target track initiation.
