论文部分内容阅读
本文内容分理论研究和实验研究两部分。首先，对高分辨目标方位估计算法IMP提出了两种改善其收敛速度的方法。利用这两种改进方法，可将原算法的收敛速度提高一倍。计算机仿真验证了改进方法的有效性。其次，针对该算法进行了水池实验研究，实验分析结果显示，IMP算法能够有效地分辨和估计非等功率的两个相干信号源。
This article divides theory and experimental research into two parts. First of all, two methods to improve the convergence speed of high resolution target orientation estimation algorithm are proposed. Using these two improved methods, the convergence speed of the original algorithm can be doubled. Computer simulation verifies the effectiveness of the improved method. Secondly, a pool experiment is carried out for this algorithm. Experimental results show that the IMP algorithm can effectively distinguish and estimate two coherent signal sources with unequal power.
