阐述了多模馈源单脉冲跟踪雷达测角系统相位测量校正方法中校相值不确定度与测量子样数量的关系。给出了该类型测角系统任意象限位置空间偏角相位计算公式,并基于此公式提出一种新的圆环全域校相方法。通过对参考信标进行环绕一整周的多点测量,能够克服传统四点相位测量校正方法校相值不确定度大、置信率低、校相结果受零点对不准影响大和多径干扰误差严重的问题,同时给出了该方法的实际测试验证结果数据。
The relationship between the uncertainty of phase value and the number of measurement sub-samples in the method of phase measurement correction for multi-mode single-pulse tracking radar goniometry system is described. The formulas for calculating the phase angle of arbitrary quadrant in this type of goniometry system are given. Based on this formula, a new method for global calibration of torus is proposed. By rounding the reference beacon around a full week of multi-point measurement, it can overcome the traditional four-point phase measurement and correction method of the school phase value of the uncertainty, the confidence rate is low, the school phase results are subject to zero and the impact of non-large multipath interference error Serious problems, at the same time gives the method of actual test validation data.
