  • 3D conformal antennas for radar applications 
    Fourtinon, L (2018)
    Embedded below the radome of a missile, existing RF-seekers use a mechanical rotating antenna to steer the radiating beam in the direction of a target. Latest research is looking at replacing the mechanical antenna ...
  • Advanced cognitive networked radar surveillance 
    Jahangir, Mohammed; Baker, Chris J.; Antoniou, Michail; Griffin, Benjamin; Balleri, Alessio; Money, David; Harman, Stephen (IEEE, 2021-06-18)
    The concept of a traditional monostatic radar with co-located transmit and receive antennas naturally imposes performance limits that can adversely impact applications. Using a multiplicity of transmit and receive antennas ...
  • Ambiguity function and accuracy of the hyperbolic chirp: comparison with the linear chirp 
    Balleri, Alessio; Farina, Alfonso (2016-07-06)
    In this paper, we derive the Ambiguity Function (AF) of a narrowband and a wideband hyperbolic chirp. We calculate the second derivatives of the squared amplitude of the narrowband Complex Ambiguity Function (CAF) and use ...
  • Baseband version of the bat-inspired spectrogram correlation and transformation receiver 
    Georgiev, Krasin; Balleri, Alessio; Stove, Andy; Holderied, M. (Institute of Electrical and Electronics Engineers, 2016-06-01)
    Echolocating bats have evolved an excellent ability to detect and discriminate targets in highly challenging environments. They have had more than 50 million years of evolution to optimise their echolocation system with ...
  • Bio-inspired processing of radar target echoes 
    Georgiev, Krasin; Balleri, Alessio; Stove, Andy; Holderied, Marc W. (2018-07-20)
    Echolocating bats have evolved the ability to detect, resolve and discriminate targets in highly challenging environments using biological sonar. The way bats process signals in the receiving auditory system is not the ...
  • Bio-inspired two target resolution at radio frequencies 
    Georgiev, Krasin; Balleri, Alessio; Stove, Andy; Holderied, Marc (IEEE, 2017-06-06)
    Echolocating bats show a unique ability to detect, resolve and discriminate targets. The Spectrogram Correlation and Transformation (SCAT) receiver is a model of the Eptesicus fuscus auditory system that presents key signal ...
  • Biologically inspired processing of radar and sonar target echoes 
    Georgiev, Krasin (2017-10-31)
    Modern radar and sonar systems rely on active sensing to accomplish a variety of tasks, including detection and classification of targets, accurate localization and tracking, autonomous navigation and collision avoidance. ...
  • Biomimetic echolocation with application to radar and sonar sensing 
    Baker, C. J.; Smith, Graeme E.; Balleri, Alessio; Holderied, M.; Griffiths, H. D. (IEEE Institute of Electrical and Electronics, 2014-03-25)
    Nature provides a number of examples where acoustic echolocation is the primary sensing modality, the most well-known of these being the bat, whale and dolphin. All demonstrate a remarkable ability to "see with sound". ...
  • Bistatic radar signature of buried landmines 
    Lombardi, F.; Griffiths, H. D.; Balleri, Alessio (IET, 2017-10)
    With the proliferation of low-intensity conflict, landmines have proven to be one of the weapons of choice for both government and guerrilla forces around the world. Recent improvements to mine technology pose increasingly ...
  • Characterisation of sidelobes for multibeam radar based on quasi-orthogonal LFM waveforms 
    Balleri, Alessio; Kocjancic, Leon; Merlet, Thomas (IEEE, 2020-06-11)
    Multibeam radars (MBRs) enable multiple independent channels by simultaneously exploiting spatial and waveform diversity. Orthogonal waveforms are employed to form multiple independent antenna beams, each one providing a ...
  • Characterization of the internal structure of landmines using ground penetrating radar 
    Lombardi, Federico; Griffiths, Hugh D.; Lualdi, Maurizio; Balleri, Alessio (IEEE, 2020-02-13)
    One of the principal limitations of employing Ground Penetrating Radar (GPR) for landmine detection is the presence of clutter, i.e. reflections from the surrounding environment which might interfere with the landmine ...
  • Coordination of optimal guidance law and adaptive radiated waveform for interception and rendezvous problems 
    Balleri, Alessio; Farina, Alfonso; Benavoli, Alessio (Institution of Engineering and Technology, 2017-02-22)
    The authors present an algorithm that allows an interceptor aircraft equipped with an airborne radar to meet another air target (the intercepted) by developing a guidance law and automatically adapting and optimising the ...
  • Deception jamming against anti-ship missiles which use doppler beam sharpening modes 
    Frazer, Gareth (2020-02)
    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 ...
  • Deception jamming against doppler beam sharpening radars 
    Frazer, Gareth; Balleri, Alessio; Jacob, George S. (IEEE, 2019-09-16)
    Missile seekers are becoming increasingly more capable of using Doppler Beam Sharpening (DBS) modes as part of the homing cycle. This paper develops jamming theory and uses it for practical implementation of inserting false ...

  • Dependence of landmine radar signature on aspect angle 
    Lombardi, F.; Griffiths, H. D.; Wright, L.; Balleri, Alessio (IET, 2017-02-06)
    Antipersonnel landmines have been indiscriminately used since World War II, and their longterm persistence in the ground creates a barrier to development in a large number of countries, forcing people to live in constant ...
