Secure Radar-Communication Systems with Malicious Targets: Integrating Radar, Communications and Jamming Functionalities [PDF]

open access: yesarXiv, 2019
This paper studies the physical layer security in a multiple-input-multiple-output (MIMO) dual-functional radar-communication (DFRC) system, which communicates with downlink cellular users and tracks radar targets simultaneously. Here, the radar targets are considered as potential eavesdroppers which might eavesdrop the information from the ...

FDA Jamming Against Airborne Phased-MIMO Radar-Part I: Matched Filtering and Spatial Filtering [PDF]

open access: yesarXiv
Phased multiple-input multiple-output (Phased-MIMO) radar has received increasing attention for enjoying the advantages of waveform diversity and range-dependency from frequency diverse array MIMO (FDA-MIMO) radar without sacrificing coherent processing gain through partitioning transmit subarray. This two-part series proposes a framework of electronic

FDA Jamming Against Airborne Phased-MIMO Radar-Part II: Jamming STAP Performance Analysis [PDF]

open access: yesarXiv
The first part of this series introduced the effectiveness of frequency diverse array (FDA) jamming through direct wave propagation in countering airborne phased multiple-input multiple-output (Phased-MIMO) radar. This part focuses on the effectiveness of FDA scattered wave (FDA-SW) jamming on the space-time adaptive processing (STAP) for airborne ...

Deception Velocity-Based Method to Discriminate Physical Targets and Active False Targets in a Multistatic Radar System

open access: yesRemote Sensing
Due to the silent operation of the receiver station in a multistatic radar system, it is difficult for the jammer to generate the cooperative active deception target for the multistatic radar system.
