“…There is very little literature on jamming DBS modes, but previous work in [31] introduced the concept of creating false targets in DBS images of a missile seeker using a varying time delay method. For this method, the jammer receives the incoming waveform and delays it before re-transmitting.…”

Missile seekers are becoming increasingly more capable of using Doppler Beam Sharpening (DBS) modes as part of the homing cycle, which requires new countermeasures against this mode. One type of countermeasure, is to create false targets within the seeker DBS image. This paper proposes a jamming technique to generate false targets at a precise location within a seeker DBS image, by both delaying and adding a Doppler shift to received waveforms. The effects of tracking errors on the position of the false target are analysed, both analytically and with simulations and used to assess the practical implementation of the jamming scheme. An experimental DBS system was built to test the effectiveness of the jamming scheme against a platform moving in steps and assess errors caused by incorrectly estimating the seeker trajectory. INDEX TERMS Anti-ship missile, DBS, false targets.

“…Detecting when the seeker would be performing DBS is beyond the scope of this paper, but the optimised trajectories give a potential method of detecting when a seeker is using DBS. There is very little literature on jamming DBS modes, but previous work in [31] introduced the concept of creating false targets in DBS images of a missile seeker using a varying time delay method. For this method, the jammer receives the incoming waveform and delays it before re-transmitting.…”
