基于SLR数据的雷达探测精度分析方法

空间安全已成为各航天大国国家安全中的重要一环，空间目标监视技术也已成为空间技术新的制高点。雷达凭借其全天时、全天候的特点，已成为空间目标监视的骨干设备，其探测精度直接影响太空态势掌控的准确性，因此准确分析雷达探测精度有着重要意义。本文以卫星激光测距（SLR）数据为基础，首先分析了不同阶数插值算法以及滑动式内插、非滑动式内插的插值精度，而后介绍了坐标转换方式与雷达精度分析方法。仿真结果表明，滑动式九阶拉格朗日插值算法有较好的插值效果，满足雷达精度分析的需求。

Radar Detection Accuracy Analysis Method Based on SLR Data

Space security has become an important factor in the national security of all major space powers. Space target surveillance technology has also become a new technical peak for space technology. Radar has become the main equipment for space target surveillance relying on its all-time and all-weather characteristics. Its detection accuracy directly affects the space situation control, so analysis of radar detection accuracy is of great significance. Firstly, the accuracies of different order interpolation algorithms, sliding interpolation, and non-sliding interpolation are analyzed based on satellite laser ranging (SLR) data. Then we introduce the coordinate conversion method and radar accuracy analysis method. The simulation results show that the sliding ninth-order Lagrange interpolation algorithm has a good interpolation effect and meets the requirements of radar accuracy analysis.
