摘　　要：在布设信号接收阵列时,阵元位置通常会受到地形等因素的限制,且随着多维电磁探测系统的构建,阵列搭载逐渐向着诸如飞行器、卫星等更加灵活的平台发展,阵列位置部署也将受到更多的约束。因此对基于灵活阵列的测向技术进行了分析和对比。同时,针对其中干涉仪算法扫描步进与测向精度反相关的技术问题,提出了一种基于曲线拟合修正的干涉仪算法,能够在较大扫描步进下保证测向精度,并通过计算机仿真验证了算法的正确性。The location of the array elements would be restricted by topography and other factors when deploying receive arrays.With the construction of the multi-dimensional electromagnetic detection system,array mounting is moving towards more flexible platforms such as aircrafts and satellites,and the location deployment of arrays would have more constraints.Therefore,the different direction finding algorithms based on flexible array are analyzed and compared.At the same time,aiming at solving the technical problem related to the inverse relationship of the scanning step and the DOA accuracy in the interferometer algorithm,an improvement method of interferometer based on curve fitting correction is also proposed,which can ensure the direction finding accuracy under the larger angle scanning step and the correctness of the algorithms is verified by computer simulations.
