摘　　要：给出了一种测速雷达信标测量多普勒频率复原的新方法,此方法与目标运动的初始轨道参数无关。与已有方法相比较,新方法解决了已有数据复原方法对初始轨道参数的依赖性,理论上消除了初始轨道参数精度对数据复原精度的影响。通过与已有方法计算结果的比对分析表明,新方法能够满足数据处理精度要求,具有较好的适用性,是实现信标测量数据复原的有效途径。A new method to restore the Doppler frequency of velocity-measurement radars in beacon measurement is presented and the method is independent of the initial orbit parameters of moving objects.Compared with the existing method,the new method eliminates dependence on initial orbit parameters and,theoretically,it removes the effect of the accuracy of the initial orbit parameters on data restoration.Comparison and analysis of the results of computation with the two methods indicates that the new method well meets data processing accuracy requirements and has excellent applicability.It is an effective approach to restoration of beacon measurement data.
