In defense technologies, "failure" has much heavier consequences than in the civilian sector. It is unacceptable for a radar to be blinded under jamming or for an avionics system to be disabled by lightning strike.
**MIL-STD-461** (Electromagnetic Compatibility) and **MIL-STD-810** (Environmental Conditions) are the cornerstones of this survivability. As Consept, we manage the complex qualification processes of platform manufacturers and subcontractors.
We provide technical support from R&D stage to PDR/CDR (Design Review) meetings, and become your solution partner with "root cause analysis" in case of failure.

Surge and spike tests for land vehicles.
Airborne environmental and EMC conditions.
Case of an HF/VHF radio system in an armored land vehicle losing communication due to severe interference when the vehicle\'s engine management system (ECU) is activated.
In the pre-test phase, when the vehicle\'s electronic control unit was active (especially during acceleration), an intense noise source in the 2 MHz to 30 MHz band deafened (desensed) the radio receiver. Conducted and radiated emissions exceeded limits by 25 dBµV/m.
By adding a multi-stage Pi (π) type EMI filter to the power supply line of the engine control unit, low frequency conducted noises (CE102) were attenuated.
Cable harnesses going to sensor networks were replaced with appropriately shielded braided cables and low impedance grounding (bonding) was made to the chassis.
After the mitigation measures taken, the armored vehicle was tested again and successfully passed RE102, CE102 and RS103 tests with a high engineering margin (staying on average 10 dB below the limit). Radio communication range returned to 100% capacity.
