\n

Plextek<\/a> has tested a way to locate radio-frequency (RF<\/abbr>) emissions with a high degree of accuracy.<\/p>\n

With Centre for Defence Enterprise (CDE<\/abbr>) funding, the company has developed an algorithm to analyse compressed RF<\/abbr> samples from multiple antennas. This will determine the frequency and bearing of an RF<\/abbr> emitter.<\/p>\n

The algorithm doesn\u2019t rely on knowledge of the signal to be detected, instead it looks for the presence of energy at a particular frequency within a time window. It can then report the angle of arrival at a much better rate than the frequency required by conventional receiver architectures. It can therefore maximise the likelihood of detecting previously unknown threats.<\/p>\n

As part of the testing, real-world emitter data was captured covering a variety of RF<\/abbr> emitter sources. These included cellular (2G, 3G) and radar (pulsed Air Traffic Control and frequency-modulated continuous-wave ground surveillance).<\/p>\n

Plextek seeks to build on the knowledge gained from this project to develop a lightweight, modular capable demonstrator, which has the potential to capture real-time RF<\/abbr> emitter sources.<\/p>\n

Plextek intends to couple the demonstrator with a narrow-band receiver to replicate a possible usage configuration for more detailed analysis.<\/p>\n

We\u2019re pleased to have continued our successful relationship with CDE<\/abbr>, securing 6 projects across 4 themed competitions in 2015. This has led to Plextek\u2019s wider collaboration within Dstl<\/abbr> and MOD, the UK Defence Solutions Centre, and across the defence supply chain.<\/p>\n<\/blockquote>\n

Plextek, based in Great Chesterford, has been at the forefront of business and product innovation since 1989 and currently employs 70 staff.<\/p>\n
