Broadcast anti-jamming systems

Computer Networks, 2001
In a traditional anti-jamming system a transmitter who wants to send a signal to a single receiver spreads the signal power over a wide frequency spectrum with the aim of stopping a jammer from blocking the transmission. In this paper, we consider the case that there are multiple receivers and the transmitter wants to broadcast a message to all ...

Anti-Jamming Radiometric Automatic Tracking System

2021 XXIV International Conference on Soft Computing and Measurements (SCM), 2021
The paper studies an anti-jamming system for automatic tracking of single vehicles. Tracking is implemented by vehicles radiation in the millimeter wavelength range. Authors synthesized tracking using statistically optimal algorithm for joint filtering of continuous and discrete Markov sequences.

Anti-jamming of chaotic signals

Proceedings of Third International Conference on Signal Processing (ICSP'96), 2002
It is found that the amplitude-modulation disturbance can make the chaotic output signals of Chua's (1986) circuit jump into a limit cycle. This is because the limit cycles usually encircle the chaotic orbits in the phase portraits of the Chua's circuits. The four jamproof methods adopted in our physical experiments are the limiter for clipping the sum

Dynamic Adaptive Anti-Jamming via Controlled Mobility

IEEE Transactions on Wireless Communications, 2013
In this paper, the mobility of network nodes is explored as a new promising approach for jamming defense. To fulfill it, properly designed node motion that can intelligently adapt to the jammer's action is crucial. In our study, anti-jamming mobility control is investigated in the context of the single and multiple commodity flow problems, in the ...

An Improved Radar Anti-jamming Method

2018 IEEE 3rd International Conference on Signal and Image Processing (ICSIP), 2018
When the interference enters from the main lobe direction of the radar, the adaptive side-lobe cancellation algorithm will lead to beam distortion, main lobe pointing offset, and affect the detection of the target. This paper proposes a phase-coded signal system.

Anti-Jamming Transmitter Independent Radar Networks

2008 International Conference on Signal Processing, Communications and Networking, 2008
A transmitter independent receiver network (TIRN) is a network of radar receivers that operates in an area without cooperating with a particular radar transmitter, but rather using transmitters of opportunity (TOA) in order to detect and track airborne, ballistic or surface targets.

Efficient uncoordinated FHSS anti-jamming communication

Proceedings of the tenth ACM international symposium on Mobile ad hoc networking and computing, 2009
We address the problem of jamming-resistant communication in scenarios in which the communicating parties do not share secret keys. This includes scenarios where the communicating parties are not known in advance or where not all parties can be trusted (e.g., jamming-resistant key establishment or anti-jamming broadcast to a large set of unknown ...

Distributed anti-jam wireless communications network

MILCOM 97 MILCOM 97 Proceedings, 2002
Motorola is investigating network architectures to support anti-jam wireless communications for the Advanced Telecommunication/Information Distribution Research Program Consortium sponsored by the U.S. Army Research Laboratory. It is envisioned that the network architecture will contain a distributed network control structure and mobile nodes.

Naval radar anti-jamming technique

Journal of the Institution of Electrical Engineers - Part IIIA: Radiolocation, 1946
The use of radar in the 1939-45 War was quickly followed by the development of methods of "jamming" radar equipments in order to reduce their operational value. Specimen photographs are shown in the paper of the appearances of various types of jamming signal on radar displays.
