Discussion of GPS Anti-Jam Technology
GPS Solutions, 1999The Global Positioning System (GPS) satellita navigation aiding system, sometimes called NAVSTAR, has become a utility to the military and many civilian areas. GPS, currently consisting of 24 satellites, is used by the military for navigation, precision weapons delivery, and the future digital battlefield.

Geographic-Based Satellite Anti-Jam Strategies
28th AIAA International Communications Satellite Systems Conference (ICSSC-2010), 2010The cancellation of the transformational Satellite (TSAT) program has created interest in commercial satellite use for military purposes. A key requirement difference between these two is the need for anti-jam (AJ) protection in military systems.

Anti-jamming Performance Analysis of FRFT-OFDM
2010 First International Conference on Pervasive Computing, Signal Processing and Applications, 2010The OFDM system based on the fractional Fourier transform (FRFT-OFDM) is robust against fast-fading channel. However, the performance of anti-jamming is not analyzed. In this paper, the anti-jamming performance of the FRFT-OFDM system under multitone jamming (MTJ) and linear frequency modulated (LFM) jamming is evaluated.

Metricwave Radar Anti-jamming Technology
2019Apart from radar signals, there are a great deal of civil television, modulation frequency radio and communication signal in crowded metricwave frequency bands, which are usually adjacent to radar operation frequency, with very high power and incessancy, therefore metricwaver radar should firstly be characteristized with anti-jamming capability in ...

Optimal anti-jamming strategy in sensor networks
2012 IEEE International Conference on Communications (ICC), 2012Wireless sensor networks have been widely applied to various application domains such as environmental monitoring and surveillance. Because of reliance on the open transmission media, a sensor network may suffer from radio jamming attacks, which is easy to launch but difficult to defend.

Anti-jamming techniques for synthetic aperture radar
2009 IEEE International Geoscience and Remote Sensing Symposium, 2009Excellent performance of SAR has aroused deep study of jamming techniques. This paper first discusses present jamming techniques and their shortcomings, then gives methodology of classifying ECCM of SAR, and at the same time, gives principle and results of signal design method, which combines orthogonal codes and random initial phase at each pulse, the

Anti-jamming on the OR-channel
Proceedings of 1994 IEEE International Symposium on Information Theory, 2002We propose a frequency hopping scheme with M-ary frequency shift keying applied to the OR-channel and give its error and erasure probabilities. Asymptotically, the bit error probability is bounded away from zero whereas it polynomially tends to zero for our previously proposed generalized scheme. >

Anti-Jamming Techniques for GPS Receivers
2001Abstract : The fundamental objective of this research project is to improve the GPS receiver performance when subjected to strong nonstationary interference. The techniques applied and proposed to achieve this objective rely on the estimation of both time-frequency and spatial signatures of the jammers.

Active Anti-jamming Solutions in CRNs
2015Cognitive radio nodes are motivated to perform jamming attacks, if the illegal gains exceed the payment due to the attacking cost and the loss from the resulting punishment. In this chapter, we present active anti-jamming solutions in CRNs, based on reciprocity principles, social norms and reinforcement learning techniques.
