Electromagnetic Remote SensingDefence Technology
Centre
  • Professor Keith Lewis
  • Research Director

2
Scope of the EMRS DTC
  • The EMRS-DTC supports
  • Research applicable to military and security
    systems that gather and process electro-magnetic
    signals, propagating in free space to a
    collecting aperture, for the purposes of remote
    sensing
  • Charter from MoD covers 6 years of activity, with
    a total budget of 30m (5m pa)
  • Matched by Contribution in Kind from industrial
    consortium members
  • It does not fund research into-
  • Acoustic systems
  • Communication systems (except for IFF)
  • Jamming systems.
  • Directed-energy damage weapons
  • Systems for detection of chemical biological
    agents
  • Data fusion algorithms
  • Other DTCs
  • Data Information Fusion
  • Human Factors Integration
  • Counter-terrorism Centre
  • Systems Engineering Integrated Systems for
    Defence Autonomous Semi Autonomous Vehicles
  • US/UK International Technology Alliance -
    research in networking and information sciences

General Strategy
  • Need to ensure that DTCs output can be seen to
    be exploited in military and/or commercial
    systems
  • Ensure the best use of Industrys Contribution in
    Kind
  • Exploit the position of the EMRS DTC in relation
    to other DTCs
  • Seek collaborative opportunities
  • Harmonise activities with other funded MoD
    programmes
  • Exploit ability of Dstl to plan trials to address
    the military context
  • Ensure the positioning of the DTCs programme in
    relation to the spirit of the Defence Technology
    Strategy (DTS)
  • Seek game-changing solutions

4
MoD Key Drivers
  • MoD has identified the following key military
    capabilities needed from future sensor systems
  • Day and night, all weather capability
  • Long range operation
  • Rapid, large area search capability
  • Detection of low signature targets
  • Detection of camouflaged / concealed targets
  • Affordable, robust systems for military platforms
  • Covert operation
  • Multi-function, detection / ID capability

At 0.4THz, the apparent temperature contrast for
a sheet of explosive hidden under light clothing
is about 2K
5
Some high priority drivers from the DTS
  • Capitalise on the UK's excellence in sensor
    technology with increased emphasis on
    multifunctionality and target recognition
  • Develop a holistic sensing capability, using
    multiple sensor types across a network of
    platforms
  • Progressively combine the functionality of
    previously separate sub-systems through shared
    apertures and processing
  • Lightweight multifunctional apertures
  • Ensure that UK Industry is able to access GaN
    technology
  • Substantial research investment required in
    countermine technologies
  • Increased emphasis will be placed on engaging the
    widest possible range of expertise and innovation
  • 3-D ground target imaging using active EO
    illumination
  • Target investment in laser sources against
    important military specific technologies
  • Work towards compact modular DIRCM
    self-protection systems to allow rapid upgrades
  • Link sensor protection research with sensor
    system suppliers through demonstrator programmes
  • Maintain an indigenous capability to develop and
    exploit Signal Processing

6
Strategy for pull-through
  • Key role of Industry-based Theme Leaders
  • RF Systems - Tony Kinghorn (Selex)
  • EO Systems - Stuart Duncan (Selex), Stephen
    McGeoch (Thales)
  • Transducer Devices and Materials - Richard Lang
    (Filtronic)
  • Transducer Embedded Processing - Bryan Rickett
    (Roke Manor)

Surveillance and Target Detection
  • Targets with low radar cross section, or which
    are wholly or partly hidden by foliage, or which
    have low contrast compared with the background,
    pose particular difficulties
  • Engagements involving missiles (both
    line-of-sight and ballistic) are particularly
    difficult, requiring detection and associated
    weapon systems with rapid response times (low
    latency)
  • Low altitude, slow moving air targets, such as
    uninhabited air vehicles and cruise missiles,
    pose particular problems of detection and
    tracking due to clutter and obscuration
  • In urban warfare, the ability to image the
    interior of buildings and locate people inside
    them would be of great value to troops, as would
    the ability to be able to detect at range
    metallic and plastic (explosive) objects carried
    under garments
  • What if
  • We could lip read at distance
  • We could tag people
  • We could identify people and their intent using
    non-visual cues
  • What sensing modalities do we need?
  • What are the networking implications?
