A Novel FDA-MIMO Deceptive Jamming Method For Neutralizing Phase Array Radar

Deceptive jamming is one of the indispensable part of electronic countermeasure technology, which has a significant role in modern warfare to secure the aircrafts from imminent threats. This research work proposes a novel Frequency Diverse Array-Multiple Input Multiple Output (FDA-MIMO) deceptive jamming method for neutralizing the opponent Phase Array Radar (PAR). The proposed deceptive jamming model works in passive mode. It interrupts the opponent radar signals and after addition of the deceptive signals, the processed signals are propagated back to neutralize the surveillance operation of the intended radar. When the opponent PAR receives these signals, it perceives multiple fake aircrafts flying at different ranges along the actual aircraft with modified and up-shifted radial velocity. Further, the proposed model uses diversification in frequencies, waveforms, and time modulation to protect the flight of the preferred aircraft. The effectiveness of the proposed model is verified through several simulations in Matlab using different number of arrays, directions and ranges.
