摘要

针对二维谱估计算法的空间探测性能分析的需求，从计算速度、计算量、顽健性、计算精度以及实际工程应用的角度出发，对基于L型阵列的二维MUSIC、二维干涉仪、二维增广矩阵束的谱估计算法进行了简要介绍，并对上述二维谱估计算法的性能进行了仿真分析，得到了3种算法的角度RMSE的对比分析，可知在同样仿真条件下，二维增广矩阵束算法最优，二维MUSIC算法次之，二维干涉算法最差。同时，构建了相应的试验场景，通过试验分析上述二维谱估计算法的空间探测性能，得到的试验结论与仿真结论一致。在此基础上，提出了二维增广矩阵束算法可扩展应用到雷达测控一体化系统的思路。

Abstract

According to the analysis requirement of the space probe performance of 2-D spectrum estimation algorithm

a brief introduction of the 2-D spectrum estimation algorithms was given in the view of calculating speed

calculating volume

stability

accuracy and practical application.These algorithms were the spectrum estimation algorithms of the 2-D MUSIC

the 2-D interference and the 2-D MEMP with the L-shaped array.The estimation performance of the algorithms were analyzed by simulations

the angle root mean square error of three algorithms were compared and analyzed.Simulation results show that the performance of the 2-D MEMP is the best

the performance of the 2-D interference algorithm is the worst

and the performance of the 2-D MUSIC is moderate.Meanwhile

the experimental scene was constructed

and the space probe performance of the 2-D spectrum estimation algorithm was analyzed by real data.The experimental results were consistent with the simulation results.Based on this

the 2-D MEMP algorithm may be further applied in the radar and TT＆C system.
