摘要
针对船载单脉冲数字接收机跟踪性能受温度相位稳定性影响的问题,分析了影响数字接收机相位变化的原因,并从理论上分析了同轴电缆温度相位稳定性与接收机跟踪性能之间的关系。基于工程试验和设备特点,提出了船载单脉冲接收机2种相位校准应对策略,通过试验验证具有一定可行性。该研究成果为船载接收机动态校相和跟踪性能研究提供参考。
To address the issue that the tracking performance of shipboard mono-pulse digital receiver is affected by the tempera- ture phase stability, the reason for digital receiver phase variation is analyzed, and the relationship between coaxial cable temperature phase stability and tracking performance is analyzed theoretically. Based on engineering test and the characteristics of equipment, two phase calibration strategies for shipboard mono-pulse receiver are proposed.The feasibility is validated by experiment.The results provide a reference for the study of shipboard receiver dynamic phase alignment and tracking performance.
