The article presents the results of integrated (physical, analytical and computer - using the method of statistical simulation modeling (SSM)) studies of the structure of the electromagnetic fields (EMF) generated by aperture random antenna (ARA) with rectangular configuration. The results of the SSM structure of EMF generated by the ARA in the frequency band 1 kHz...5 GHz are given. The baseline conditions for the development of SSM-model of real ARA in harmonic mode are defined. The conditions wherein it is possible to use the term «phase error» performing the SSM are considered in the article. The methodology for choice of limit values of the «phase error» is proposed. At frequencies below 100 MHz a phase error in the ARA can be neglected; at frequencies of 0,1...1 GHz maximum phase error increases from zero to 180°; at frequencies above 1 GHz the phase error is uniformly distributed on the interval [-180°; 180°]. Cluster method of between-error correlation in the multielement ARA was used during the SSM. At frequencies below 1 GHz the cluster dimensions coincide with the dimensions of one element ARA. At frequencies above 1 GHz, the number of clusters for a single element ARA equals four. Mathematical model and SSM-model EMF ARA-generated are presented in the article. The results of the SSIM in the frequency band 1 kHz...5 GHz in the form of histograms of random values of the level of EMF ARA-generated are presented.
