Deceptive jamming suppression with frequency diverse MIMO radar

Signal Processing, 2015
Simulated 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 ...

A deceptive jamming method against MMW monopulse radar

2009 International Conference on Microwave Technology and Computational Electromagnetics (ICMTCE 2009), 2009
This article focuses on MMW monopulse radar seeker and its deceptive jamming technique. Based on the principle of stepped-frequency high range profile monopulse seeker, a method of jamming against stepped-frequency high range profile monopulse seeker is proposed.

Target Reconstruction in Deceptively Jammed SAR via ADMM

IEEE Sensors Journal, 2019
This 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).

SAR deception jamming identification via differential feature enhancement

2016 CIE International Conference on Radar (RADAR), 2016
This paper proposes a new scheme for SAR deception jamming identification using single channel data. The time-frequency distributions of the real echoes and the deception jamming are modeled according to their formatting mechanisms. By filtering in the Doppler frequency domain, the differential features of the real and the false targets are retained ...

Target Reconstruction From Deceptively Jammed Single-Channel SAR

IEEE Transactions on Geoscience and Remote Sensing, 2018
This paper considers the problem of reconstructing true targets in a single-channel synthetic aperture radar (SAR) imaging system, which has been disturbed by deceptive jammings. Since the deceptive jammings are usually confined to the main lobe of an SAR antenna, their time–frequency distributions are different from those of the true echoes.

Single Receiver Against Repeater Deception Jamming Technology Research

2017
Intentional deception jamming brings great threat to satellite navigation receiver and seriously influence GNSS application security. For repeater deception jamming, an anti-spoofing algorithm based on a single receiver is proposed. Using the adjacent two times measurement pseudo-range does double differences, and Taylor expansion is applied to the ...

The Effect of Jamming/Deception on Decision Making

1984
Abstract : The present experiment examined the capability of developing a simulation methodology for assessing the effects of Command, Control, and Communications CounterMeasures (C3CM) on a human operator. Primarily, the effects on human information jamming and deception were applied against a key decision maker in a simulated, air defense, C3 system ...
