Research on the Compound Jamming Method against FDA-MIMO Beamforming

open access: yesApplied Sciences, 2022
Frequency diverse array multiple-input multiple-output (FDA-MIMO) radar solves the problem of angle pointing and range pointing during beam transmission due to its unique range-angle dimension dependent, which gives it good characteristics against main ...

Improved MUSIC Method against Range Dimension Deceptive Jamming Based on FDA-MIMO

open access: yesApplied Sciences, 2022
Frequency diverse array-multiple-input multiple-output (FDA-MIMO) radar makes it transmit beam range–angle two-dimensional freedom by attaching a small frequency offset increment between the array elements.

An Anti-Jamming Method against Two-Dimensional Deception Jamming by Spatial Location Feature Recognition [PDF]

open access: yesSensors, 2021
Interrupted sampling repeater jamming (ISRJ) is an effective method for implementing deception jamming on chirp radars. By means of frequency-shifting jamming processing of the target echo signal and pulse compression during image processing, a group of false targets will appear in different spatial locations around the true target.

Deception Jamming Against Doppler Beam Sharpening Radars [PDF]

open access: yes2019 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

Deceptive Jamming Algorithm against Synthetic Aperture Radar in Large Squint Angle Mode Based on Non-Linear Chirp Scaling and Low Azimuth Sampling Reconstruction

open access: yesRemote Sensing, 2023
Due to the complex range migration characteristics of large squint angle synthetic aperture radar (SAR), it is difficult for traditional SAR deceptive jamming algorithms to balance focusing ability and computational efficiency.

Research on main‐lobe deceptive jamming against FDA‐MIMO radar

open access: yesIET 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

open access: yesLeida 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 ...
