Deception Jamming Against Doppler Beam Sharpening Radars

Doppler Weather Radars and Wind Turbines

In many countries the number of wind turbines is growing rapidly as a response to the increasing demand for renewable energy. The cumulative capacity of wind turbines worldwide has shown a near 10-fold increase in the last decade (Global Wind Energy Council, 2011) and in the coming years many more wind turbines are expected to be built. Existing, older wind turbines are likely to be replaced by...

Multifrequency OFDM SAR in Presence of Deception Jamming

Orthogonal frequency division multiplexing (OFDM) is considered in this paper from the perspective of usage in imaging radar scenarios with deception jamming. OFDM radar signals are inherently multifrequency waveforms, composed of a number of subbands which are orthogonal to each other. While being employed extensively in communications, OFDM has not found comparatively wide use in radar, and, ...

Practical Defenses Against Storage Jamming

Storage jamming [15] is malicious but surreptitious modification of stored data, to reduce its quality. The person initiating the storage jamming does not receive any direct benefit. Instead, the goal is more indirect, such as deteriorating the position of a competitor. We assume that a Trojan horse does the storage jamming, since the Trojan horse may access data that the attacker cannot. Manua...
