| Description | The main output of the research is a novel technique to insert false targets in a radar image which was acquired using Doppler Beam Sharpening (DBS). Specifically, a technique to insert a false target at a precise location within a DBS image against an Anti-Ship Missile which is using a DBS mode for acquiring targets. In order for a jammer to induce a false target within a missile seeker DBS image, it requires knowledge of the missile trajectory, as well as the ability to coherently modify the missile seeker waveform. A jamming scheme was derived to detail exactly how the jammer should modify a missile seeker waveform to place a false target at a desired location. An experimental setup capable of taking DBS images and demonstrating jamming was designed and built as part of the research. The experimental data gained through this set up proved the jamming scheme to be accurate and effective, when all parameters of the scenario (e.g. missile trajectory, waveform variables, etc) are known. This jamming scheme was then analysed to assess the performance of the jammer when parameters of the scenario were incorrectly estimated by the jammer. |
| Exploitation Route | The Marine and Defence sectors could build on this research in a number of ways: Missile seeker designers could take these jamming techniques into consideration to make their seekers more robust to jamming. Electronic CounterMeasures (ECM) designers could incorporate the jamming methods into their jammers to protect ships and ground based targets against missiles using Doppler Beam Sharpening. |
