Abstract

A modern artillery use a FMCW Proximity Fuze for effectively target destruction. FMCW Proximity Fuze can be deceived by Jamming Technique because it uses RF for distance estimation. FMCW Proximity Fuze algorithm is similar to FMCW radar's, but normal Jamming Tech. like Noise and Mulitone is useless. Most Shots with FMCW Proximity Fuze have a additional mechanical fuze against RF Jamming. Shots explode by mechanical fuze when Proximity Fuse is Jammed. However, distance Deception is available because shots can not distinguish between deception jamming signal and ground reflected signal. For making Distance Deception Jamming, FMCW signal tracking is demanded. In this paper, we propose a FMCW tracking method and develop the Jammer to show Jamming signal.

Key Words: Deception Jamming, FMCW
