Three types of electromagnetic environments are considered in this analysis. The first is improper command Spoofing which is intended to cause the DCDRS airborne vehicles to carry out an unsuccessful or abortive mission. Another is random electromagnetic signals that are generated either internally or externally to cause a degradation of performance or failure of equipment. These signals occur in the form of electromagnetic interference EMI or an electromagnetic pulse EMP. The third environment, TEMPEST, is inadvertent transmission of secure information that may be recovered by unauthorized persons. This analysis considers various design approaches to minimize or eliminate the affect of these environments on DCDRS equipment. Anti-spoofing is accomplished by using encryption devices to provide for secure transmission of command and guidance information. EMI, EMP, and TEMPEST control are accomplished by proper design techniques such as grounding, shielding, filtering, component selection, and routing. Circuit analysis and problem prediction also help control the affect of these environments.
