High power electromagnetic weapons transmit microwave energy to disturb the air targets with desired engagement power. İnitially, the air target is engaged by high power electromagnetic weapon. Any material conducting electricity at air target connects with microwave transmitted from the weapon and stimulates electron flow in the unit. Consequently, the target’s conductive materials act like little antennae, gathering the high power of the weapon and channel electron flow through the air platform. Then, transient and voltage currents generate specious signals that confuse the system and damage sensitive components.
Four missions can be carried out by high power electromagnetic weapons: upset, lockup, latch-up, and burnout. Upset is a temporary alteration sensor nodes, so the air target losses lock because of interference. Upset and lockup produce the comparable effects. However, in lockup, the effects of the weapon continue even after the signal is removed. The air target cannot operate until the system is rebooted. Latch-up overloads the system with microwave radiation and causes blowing of fuses or transistors on critical circuit boards of air targets. Burnout is the physical destruction by melting small wires or junction nodes. As a result of melting and fusing multiple wires, electrical arcing occur and damage the onboard electronics. Although burn out is more effective than upset, the energy requirements are tremendously different. Upset can be carried out with 0,1W or less while burnout requires ~100W of power.
High power electromagnetic weapons can reach vulnerable components of the target via targets sensors -antenna or seeker head-, or indirectly -the target's body-. The direct approach is called ‘front-door coupling,’ and the indirect is named ‘back-door coupling.’ If the target system’s receiver is operating in known frequency, same as the weapon, the front-door coupling is suggested. Since the target’s antenna is designed and tuned to pick up signals of known particular bandwidth, will be vulnerable to malicious signals. If the limiting devices protecting the receiver is not state-of-the-art and sufficient, it is possible to inflict damage to the electronic systems.
On the other hand, back-door coupling penetrates the skin of the target system inflicts damage on the target’s electronics. Once inside the target system microwaves generated by high power electromagnetic weapons cause drastic issues for the circuitry. However, penetrating through the target’s protective casing requires more power than front-door coupling.
At Belpico, we are developing microwave generators for future high power electromagnetic air defence systems. Microwave generators coupled with precision targeting can engage the targeted systems with remarkable accuracy; even targets are near friendly forces. Also, infinite magazine technology can fire as long as enough electricity is supplied. Another critical point, microwaves travel at the speed of light. The light speed travel provides an exceptional advantage in countering high-speed attacks as the system can engage various high-speed targets within a short period. As a result, microwave generators for future high power electromagnetic air defence systems are effective in countering high-speed, swarming, and salvo attacks. Furthermore, rapid engagement leaves little or no time for countermeasures. We regard our microwave generators are the future for next generation high power electromagnetic air defence systems.
