Deceptive jamming suppression with frequency diverse MIMO radar
Signal Processing, 2015Simulated false targets cannot be easily discriminated and suppressed with traditional radar systems, especially for the mainbeam deceptive jamming. In this work, we explore the multiple-input multiple-output (MIMO) radar with frequency diverse array (FDA) as the transmit array and study its ability to suppress the deceptive jamming in joint transmit ...

Target Reconstruction in Deceptively Jammed SAR via ADMM
IEEE Sensors Journal, 2019This paper formulates an alternating direction method of multipliers (ADMM) approach to reconstruct true and false targets in a deceptively jammed synthetic aperture radar imagery based on characteristics extracted by dynamic synthetic apertures (DSAs).

A Novel Anti-Deceptive Jamming Method for Multistatic SAR
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Multistatic synthetic aperture radar (SAR) have achieved significant performance in the field of anti-jamming for its flexible configuration. Hence, its capacity of anti-jamming is very important in electronic warfare. In addition, it is difficult to remove the false targets caused by the deceptive jammer from SAR echoes.

An effective method of active deception jamming for countering ISAR
2013 IEEE Third International Conference on Information Science and Technology (ICIST), 2013To improve the efficiency of the jamming signal generation, a jamming signal generation method based on ISAR echo model is proposed. According to the jammer's position as well as the false targets' expected position, this method calculates the false targets' every minimum resolution cell approximate delay time and its accurate phase compensation, then ...

Design and implementation of a deception jamming system for laser receivers
SPIE Proceedings, 2016Laser jamming has two forms: passive and active jamming. In this paper we compare between the passive, active and passive-active deception techniques from the functional point of view. Passive jamming techniques are used with highly absorptive or diffusive materials on the body of the equipment.

Novel Discrimination Algorithm for Deceptive Jamming in Polarimetric Radar
2012A discrimination algorithm for extracting targets in the deceptive jamming environment is proposed in this paper. While the Sinclair Scattering Matrix (SSM) of radar target correlates with the operating frequency, the SSM modulated on the decoy in the jammer is conventionally stored in memory and is independent with frequency.
