The work carried out modeling of electromagnetic compatibility in the development of hermetic and conformal enclosures of radio electronic systems. The scheme of the hermetic and adapted body of the mobile radio control station has been developed. A mathematical model for the penetration of a pulsed electromagnetic wave into the equipment screen is proposed, which differs in that it takes into account its multilayer nature and the presence of inhomogeneities in the form of holes. A method is proposed for calculating voltages and currents induced by a pulsed electromagnetic field in a shielded cable of finite length, characterized in that it takes into account the presence or absence of screen grounding at the ends. A simulation method has been developed for testing the noise immunity of radio electronic devices using software models of digital and microprocessor components and an external noise simulator. Shielding of electronic equipment was carried out as a method of ensuring electromagnetic compatibility.
