Slide 7 of 41
Overview of potential research topics (1)
• Topic 1: Classification of airborne/maritime targets using High Range Resolution (HRR) profiles, High Doppler Resolution (HDR) profiles and/or inverse Synthetic Aperture Radar (ISAR) images:
Development of a target feature database and a set of robust algorithms that use HRR profiles, HDR profiles and ISAR images to extract key features for classification purposes
• Topic 2: Synthetic Aperture Radar (SAR) imagery classification:
Automatically classifying objects of interest, such as roads, fences and vegetation
Slide 8 of 41
Overview of potential research topics (2)
• Topic 3: Radar Cross Section (RCS) modelling of targets and using different scattering mechanisms to aid with classification:
Understanding the different types of scattering mechanisms from complex targets and investigating how this information can be used to aid with classification
• Topic 4: Characterization of Doppler returns for ground-based radar:
Modelling and/or characterization of Doppler returns from animals and vegetation in order to distinguish various characteristics of targets based on long dwell-time Doppler measurements
Slide 9 of 41
Overview of potential research topics (3)
• Topic 5: An investigation of the appearance of different Electromagnetic (EM) scattering mechanisms in radar imaging techniques such as SAR and ISAR:
Investigate the appearance of more realistic EM scattering as observed through SAR and/or ISAR processing in order to qualify the artefacts produced, as well as identifying methods to improve the integration gain for non-point-target-like scattering.
• Topic 6: Analysis of the correlations between ship motion (dynamics) and sea conditions as a function of ship size and shape
Investigate whether motion data measured by a radar can be coupled to physical parameters of a ship
Slide 10 of 41
Overview of potential research topics (4)
• Topic 7: Multiple scatterer tracking and parameter estimation in HRR profile data:
Tackling the problem of tracking individual scatterers and possibly matching them to scatterer models, which is the next step in solving the single aperture 3D ISAR problem
• Topic 8: Optimisation of automated decision making for radar waveform and antenna control of mechanically scanned radars:
Study into techniques for jointly controlling a mechanically scanned radar’s beam and waveform with the aim of optimising detection, tracking and classification performance jointly
• Topic 9: Model matching of moving objects to their u-Doppler spectrum :
Develop a model based approach to target classification with the idea of also being able to reconstruct object behaviour
Slide 11 of 41
Overview of potential research topics (5)
• Topic 10: The use of radar to detect rock falls in mines:
Can a radar help with the problem of early detection of cracks in a mine roof structure ?
• Topic 11: Design of an urban (possibly low frequency) ground-based SAR for imaging and mapping informal rural areas:
Develop a cheap way of mapping rural areas
• Topic 12: Comparison of traditional phased array and MIMO radars:
Investigate performance trade-offs between classic phased array radars and MIMO radars
Slide 12 of 41
Overview of potential research topics (6)
• Topic 13: Comparison of Classification Fusion techniques (textual based fusion):
Investigate Dempster-Schaefer vs. Bayesian approaches
• Topic 14: Improving Track Fusion:
Improvement through the use of classification information
