| 摘要: |
| 双通道接收机是测控雷达实现大姿态飞行目标跟踪测量的常规设备，也是高精度雷达通用的链路配置形式。采用常规的距离零值标校方法对该类型系统进行标校，稳定性较差，精度不高，无法达到亚米级距离零值的校准目的。在传统标校方法的基础上，融合双通道相位同步修正技术，优化了系统距离零值标校方法。仿真和测试结果结果表明，50 dB动态条件下零值校准精度优于1 m，弥补了传统标校方法的不足，可以作为工程方法推广使用。 |

| Abstract: |
| The dual-channel receiver is a conventional device for tracking,telemetry and control(TT&C) radar to achieve the tracking of large attitude flight targets and it is also the universal link configuration form of high-precision radar.The conventional zero-range value calibration method,which is used to calibrate this type system,has poor stability and low accuracy and can not achieve the goal of sub-meter zero-range value calibration.On the basis of the traditional calibration method,the system zero-range value calibration method is optimized by combing the dual-channel phase synchronization correction technology.The results of simulation calculation and engineering test show that the zero-range value calibration accuracy is better than 1 m under 50 dB dynamic condition,which makes up for the shortcoming of traditional calibration methods and can be widely used as engineering method. |
