Multifrequency OFDM SAR in Presence of Deception Jamming [PDF]
EURASIP Journal on Advances in Signal Processing, 2010 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.

Deception Jamming Against Doppler Beam Sharpening Radars [PDF]
2019 IEEE Radar Conference (RadarConf), 2019 Missile seekers are becoming increasingly more capable of using Doppler Beam Sharpening (DBS) modes as part of the homing cycle, which requires new countermeasures against this mode. One type of countermeasure, is to create false targets within the seeker DBS image. This paper proposes a jamming technique to generate false targets at a precise location

Research on main‐lobe deceptive jamming against FDA‐MIMO radar
IET Radar, Sonar & Navigation, 2021 A multiple‐input multiple‐output (MIMO) radar with frequency diverse array (FDA) produces a range‐angle‐dependent steering vector, which can suppress the deceptive jamming in joint range‐angle domain.

One-bit Multi-modality Jamming Method against SAR
Leida xuebao, 2022 This paper proposes a one-bit multi-modality jamming method against Synthetic Aperture Radar (SAR). After being intercepted by the jammer, the SAR signal is quantized to one-bit sampling data through comparison with the single-frequency threshold ...

SAR deceptive jamming target-detection method based on multi-angle SAR images
The Journal of Engineering, 2019 Deceptive jamming is an effective jamming method for synthetic aperture radar (SAR). Time-delay repeater jamming, which is an important method of deceptive jamming because of its simplicity and effectiveness, can generate false targets in the SAR image ...
