摘　　要：提出一种针对连续波测量系统测速数据时间不对齐误差的自适应修正方法。在多源信息融合处理解算飞行器轨迹时,将连续波测速数据的时间误差作为待估参数求解。建立飞行器轨迹参数和时间误差的联合求解模型,采用分步优化法给出飞行器轨迹参数和连续波系统中各单台设备的时间误差估计值。实验结果表明:测速数据修正后,匹配程度明显优于修正前,飞行器轨迹参数的计算精度得到显著提高。An adaptive time-error correction method for the velocity element of continuous wave（ CW）radar measurement system is proposed in this paper. When the multi-source data fusion method is used to calculate the trajectory of aircraft,the time-error in velocity measurement of the CW radar is treated as a parameter to be estimated. The combined computation model for the trajectory parameters and time-error is constructed. By using stepwise optimization method,the trajectory parameters and the time-error in velocity measurement of each single device are jointly estimated. The experiment results indicate that the corrected velocity matches the real value,and the estimation accuracy of trajectory parameters is highly improved.
