Zhou Yu-min · Radio Engineering · 2013
The vehicle-mounted communication countermeasure system has the characteristics of high-power jamming,high sensitivity receiving,high integration and coexistence of countermeasure equipment and communication equipment.The six transmission paths of electromagnetic interference of the vehicle-mounted communication countermeasure system are analyzed in order to solve the problem of system EMC.Design of grounding,cable shielding and machine shielding,and aspects of power filter,electromagnetic spectrum planning and antenna isolation are considered in the solutions of system EMC.The measures of system EMC are given by theory analysis and corresponding calculation method.The measures are tested in the engineering practice and can guide the design of system EMC effectively.
