  • A comprehensive investigation of retrodirective cross-eye jamming 
    Du Plessis, W.P. (Warren Paul) (University of Pretoria, 2010-06-14)
    Cross-eye jamming is an Electronic Attack (EA) technique that induces an angular error in the radar being jammed. The main benefit of cross-eye jamming is that it is effective against monopulse tracking radars, which are ...
  • Cross-eye gain in multiloop retrodirective cross-eye jamming 
    Du Plessis, W.P. (Warren Paul) (Institute of Electrical and Electronics Engineers, 2016-04)
    The simultaneous use of multiple retrodirective cross-eye jammers is analysed for both the case where the jammer loops point in different directions and when they point in the same direction. In both cases, the use of ...
  • Extended analysis of retrodirective cross-eye jamming 
    Du Plessis, W.P. (Warren Paul); Odendaal, J.W. (Johann Wilhelm); Joubert, Johan (Institute of Electrical and Electronics Engineers, 2009-09)
    An extended and rigorous analysis of retrodirective cross-eye jamming in a radar system scenario is presented. This analysis removes the approximations that limit the validity of other analyses of cross-eye jamming. These ...
  • Implementation and testing of a retrodirective cross-eye jammer 
    Pieterse, Frans-Paul; Du Plessis, W.P. (Warren Paul) (Institute of Electrical and Electronics Engineers, 2022-10)
    One of the few electronic attack techniques that can deceive radars in angle is cross-eye jamming, which mimics the naturally-occurring phenomenon glint. The extreme tolerance requirements of cross-eye jamming mean that a ...
  • Path-length compensation in multi-loop retrodirective cross-eye jamming 
    Du Plessis, W.P. (Warren Paul) (Institute of Electrical and Electronics Engineers, 2019-02)
    Multiloop retrodirective cross-eye jammers offer the possibility of both simplifying system implementation and improving system performance. However, the signals for each jammer loop propagate along different paths, leading ...
  • The practical implementation of a retrodirective cross-eye jammer by using software defined radio (SDR) 
    Pieterse, Frans-Paul (University of Pretoria, 2022)
    Radar-guided missiles have the potential to cause extreme damage to vital military assets. Although traditional deception techniques can deceive radars in range and Doppler shift, only a few methods can deceive them in ...
  • Statistical skin-return results for retrodirective cross-eye jamming 
    Du Plessis, W.P. (Warren Paul) (Institute of Electrical and Electronics Engineers, 2019-10)
    The effect of the radar skin return from the platform on which a cross-eye jammer is mounted is significant in many practical cross-eye jamming scenarios. However, all published analyses of skin-return affected cross-eye ...
  • Time-interleaved jamming 
    Claassen, Gert (University of Pretoria, 2022)
    Modern jamming systems are faced with the reality that multiple threat radars will be encountered simultaneously, and potentially, all simultaneously-encountered threat radars will need to be countered to prevent detection. ...
  • Tolerance analysis of cross-eye jamming systems 
    Du Plessis, W.P. (Warren Paul); Odendaal, J.W. (Johann Wilhelm); Joubert, Johan (Institute of Electrical and Electronics Engineers (IEEE), 2011-01)
    The matching required between the two directions through a retrodirective cross-eye jammer is considered using both the traditional phase-front analysis and an extended analysis. The design parameters to achieve a specified ...
