Path-Length Effects in Multiloop Retrodirective Cross-Eye Jamming

Abstract

Cross-eye jammers are required to operate in their near-field regions, so path-length differences between the jammers comprising a multiloop retrodirective cross-eye jammer cannot be ignored. The effects of these path-length differences are investigated and are shown to be significant in realistic cross-eye jamming scenarios. Notably, path-length differences have the potential to cause a multiloop retrodirective cross-eye jammer to act as a beacon rather than a jammer when the path-length difference is approximately 180 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> .
