摘　　要：在分析单脉冲跟踪系统特性的基础上,阐述了海上自动校相的重要性,说明了目前几种海上自动校相方案的不足,以及单脉冲跟踪方式与圆锥扫描跟踪方式的优缺点,并从工程应用的角度提出了基于双跟踪方式实现海上自动校相的方案。此方案充分利用了2种跟踪方式的优点,有效克服其缺点,实现了单脉冲跟踪系统海上自动校相,且使2种跟踪系统在硬件上高度共享,馈源网络实现兼容。此外,该方案大量采用现有成熟技术,有效降低技术风险性。Based on the analysis of the characteristics of tracking system of mono-pulse, this paper describes the importance of automatic digital phase correction on sea, points out the shortcomings of several methods of automatic digital phase correction on sea as well as advantages and disadvantages of tracking of mono-pulse and conical scanning, then proposes the method of realizing automatic digital phase correction on sea based on double-tracking in view of the engineering applications. The method fully utilizes the advantages of the two tracking modes, effectively overcomes their shortcomings and realizes automatic digital phase correction on sea of mono-pulse tracking system. The two tracking systems realize a high degree of sharing in the hardware and the compatibility of feed net. In addition, the method uses a large number of existing mature technologies, effectively reducing the technical risks.
