以前的脉冲跟踪雷达幅相一致性标定过程繁琐、标定环境受限。多模自跟踪雷达建立了天线偏离角与输出角偏差信号大小关系的数学模型,通过获取被跟踪目标相对天线角度变化值以及角偏差电压变化值,形成了幅相一致性标定的新方法,对提高幅相标定效率、克服标定环境局限性等具有重要的应用价值。

The previous calibration method of the amplitude and phase consistency, which is used on the monopluse radar, has some weak points, such as the performable process being complex and the calibrating environment being limited. Multi-mode tracking established a mathematical model of the relation between deviation angle and error voltage, through obtaining the variational value of deviation angle and error voltage, a new method is determined, which is used to calibrate the amplitude and phase consistency. It has important application value for improving the efficiency of the amplitude and phase calibration, as well as overcoming the limitation of the calibrating environment.
