1简介        迭代自适应法(IterativeAdaptiveApproach，IAA)估计算法最早由美国的电气工程师和数学家RobertSchmidt和RoyA.Kuc在1986年的一篇论文"MultipleEmitterLocationandSignalParameterEstimation"中首次提出了这一算法，IAADOA估计算法是一种用于无线通信和雷达系统中估计信号到达方向的方法，对于信号处理和通信领域具有重要意义。      对于实际的雷达DOA估计来说,传统的延时相加方法(Delay-And-Sum,DAS)分辨率低,旁瓣干扰大。而ESPRIT2I和MUSIC等方法只有在

我在MongoDB中有一个集合，如下所示:{"_id":1,"parent":1,"input":[{"name":"IAA1","value":"IAA1Value3","displayOrder":1},{"name":"IAA2","type":"IAA2Value4","displayOrder":2}]}{"_id":2,"parent":1,"input":[{"name":"IAA1","value":"IAA1Value3","displayOrder":1},{"name":"IAA2","type":"IAA2Value4","displayOrder":2},{"
