A method for separation of the field contributions generated by multiple noncorrelated sources is proposed. The measurements are implemented using one scanning probe and one (or more) stationary reference probe, avoiding the requirement to measure the spatial correlations of the random fields. The contribution of each source can be determined with the assistance of the blind source separation technique. Averaging over realizations allows to cancel the uncorrelated part in the mixed signal measured by the scanning probe. The separated results can be used to localize the emission sources and their contribution to the field pattern. The method was tested on different signals with amplitude and frequency modulation with passive (antenna) and active (IC) sources.

使用盲源分离法对多个非相关源进行近场扫描

提出了一种用于分离由多个非相关源产生的场贡献的方法。使用一个扫描探头和一个（或多个）固定参考探头进行测量，避免了测量随机场空间相关性的要求。可以在盲源分离技术的帮助下确定每个源的贡献。实现上的平均允许消除由扫描探头测量的混合信号中的不相关部分。分离的结果可用于定位排放源及其对场图的贡献。该方法在具有无源（天线）和有源（IC）源的幅度和频率调制的不同信号上进行了测试。
