摘　　要：温度相位稳定性是同轴电缆的一项固有指标,该指标会影响船载单通道单脉冲数字跟踪接收机的相位。文章基于单通道单脉冲原理分析了影响接收机相位变量因子,并从理论上分析了同轴电缆温度相位稳定性与接收机相位之间的关系。基于数据拟合方法,提出了船载跟踪接收机两种相位校准策略,通过试验验证具有一定可行性和可靠性,该研究成果为船载接收机动态校相具有一定指导意义。Temperature phase stability is a natural indicator of coaxial cable, the index will affect phase of single channel monopulse tracking digital receiver on ship-board. On the basis of the principle of single channel monopulse, the article analyses the variable factor of influence receiver phase, and the relationship between temperature phase stability and receiver phase from theoretically. Based on data fitting method, two phase calibration strategy of the shipboard mono-pulse receiver is proposed. The feasibility is validated by experiment. The research provides certain guiding significance for shipboard receiver dynamic phase alignment.
