How to realize and apply radar jamming

Therefore, the deception jammer can match its operating cycle to the operating cycle of the victim radar instead of using the 100% duty cycle required of a noise jammer. To be effective, a deception jammer's power requirements are dictated by the average power of a radar rather than the peak power required for a noise jammer. In addition, since the jammer waveform looks identical to the radar's waveform, it is processed like a real return. The jamming signal is amplified by the victim radar receiver, which increases its effectiveness. The reduced power required for effective deception jamming is particularly significant when designing and building self-protection jamming systems for tactical aircraft that penetrate a dense threat environment. Deception jamming systems can be smaller, lighter, and can jam more than one threat simultaneously. These characteristics give deception jammers a great advantage over noise jamming systems.

Application principle of uav jamming equipment

In order to jam, the Jammer transmits RF power (CW + Modulation) in the same frequency used by the enemy’s link or network. The enemy’s receiver (the side that “listens”) shall receive both the Jammer’s transmission and its “partner's” transmission. The stronger one shall prevail; if the Jammer power is higher than the “partner's” power, the “listener” will not be able to “understand” correctly the message/data. Alternatively, if the “partner's” power is higher than the Jammer’s power, the “listener” will probably be able to “understand” correctly the message/data, and the communication link between the “partners” shall continue uninterrupted. This explanation is a bit superficial, and intended for simplifying things.
