提出了一种基于复杂辐射结构辐射切向电磁场时域平面近场扫描的随机电磁干扰源定位算法。在物平面的场重建的主要理论方面，以及扫描参数的主要限制也讨论了拟议的定位程序。利用两点平面扫描系统获得的自相关函数和互相关函数，可以表征随机场的分布。在此基础上，给出了一个点源频域和空域定位的实例。
Localization algorithm for stochastic EMI sources based on time domain planar near-field scanning of tangential electromagnetic field components emitted by a complex radiated structure is presented. The main theory aspects of the field reconstruction in the object plane as well as the main limitations for scanning parameters are also discussed for the proposed localization procedure. The autocorrelation and cross-correlation functions obtained by using the two-point planar scanning system are used for the characterization of stochastic field distribution. An example of point sources localization both in frequency and spatial domain is presented based on the modeling and measurement results.
