| 中文摘要: |
| 机载雷达数据处理系统需要频繁使用大地坐标变换算法将测量数据转换到公共参考坐标系下。针对精度要求相对较低的机载预警雷达系统，本文提出一种近似大地坐标变换算法以解决常规算法的计算复杂度大、难以实现等问题。Monte Carlo仿真结果表明：本文所提算法精度损失较小，计算复杂度低 |
| 英文摘要: |
| The earth coordinate transformation algorithm is employed frequently to transform the measured data to uni-coordinate in airborne radar data processing system. Classical transformation algorithms have heavy computation burden and are hard to be implemented. A approximate algorithm of earth coordinate transformation is proposed to solve above-mentioned problems for the airborne radar data processing system with predefined accuracy requirements. Experimental results of Monte Carlo demonstrate that the proposed algorithm has small loss of accuracy and low computation burden |
