5th International Conference on
Synthetic Aperture in Sonar and Radar
6-8 September 2023
Villa Marigola, Lerici,  Italy


The Institute of Acoustic has previously held four successful international conferences on Synthetic Aperture Sonar and Radar. These drew together people from both communities to discuss the developments in both fields and to establish where there are common areas of interest and where cross-fertilization may prove beneficial.

Traditional Sonar and Radar both emerged during the early parts of the 20th century and it was recognised there were many areas of common interest. These include; detection, classification, localisation and tracking of targets against a background of reverberation, noise or clutter, using either acoustic or electromagnetic energy.

Over the past few decades there have been significant advances in both domains in the use of synthetic aperture imaging techniques – in radar for high resolution imaging from aircraft and satellites, for defence surveillance purposes, for geophysical and oceanographic remote sensing and for environmental monitoring. In Sonar it has been applied in high resolution imaging of objects on the seabed (including clutter) for the offshore industry and maritime mine countermeasures.

Despite these common goals there had previously been very little cross-fertilization between the two communities and the first three IOA conferences on this topic were held in order to try and address this. 

The aim of this 2 ½ day conference is to build on the success of the previous conferences and provide a forum for comparison of systems techniques, signal and image processing, experimental results and to stimulate new ideas in each domain.

Particular topics of interest for conference are, but not restricted to:

• Synthetic Aperture from Autonomous vehicles ( AUVs and UAVs)
• Processing schemes and algorithms
• Image registration, fusion and reconstruction
• Automated and computer aided target recognition, Computer aided detection and classification
• Interferometry and differential interferometry
• Change detection
• Compressed sensing
• Performance assessment
• Low frequency and UWB synthetic aperture
• Bi-static, multi-static and MIMO synthetic aperture
• Passive synthetic aperture sonar
• Satellite synthetic aperture radar
• Motion compensation, navigation and autofocus
• Spotlight and squint mode
• Propagation effects

Prospective authors are invited to submit a title and single page abstract to by 3 February 2023.

Authors will be notified by 3 March 2023 and invited to submit a full paper by 3 July 2023.

Papers will be refereed. Completed papers may be up to 8 pages long, including diagrams and must be prepared in the correct electronic format.
