Research on radiation emission limits of airborne equipment

This paper introduces a method of estimating the airborne equipment radiation interference and calculating radiation emission limit. According to the uniqueness theorem of electromagnetic field, the model of the radiation source are described, which is theoretically proved that it is equivalent to the radiation source. The method is present with a practical engineering example,which establish a platform model and equivalent source model. Combined with microwave network theory and numerical simulation software, the radiation interference to the shortwave radio receiver is predicted. In order to satisfy the compatibility of shortwave radio receiver, the radiation emission limit of the interference source is calculated. Finally, the process and method of the equivalent source model of tailoring radiation emission limit is summarized; which can help the engineering set the emission limit and unsure the compatibility of the near-by airborne equipment.
