Australia And India Begin Collaborative Project

To boost underwater surveillance tech, India and Australia have kicked off a 3 year collaborative research project.

The first project is all about enhancing the early detection and monitoring of submarines and autonomous underwater vehicles.

This initiative marks the newest step in boosting maritime domain awareness collaboration between Australia and India.

As per a statement from the Australian Government’s Defence department, this agreement sets the stage for a three-year collaborative research initiative between the Defence Science and Technology Group’s (DSTG) Information Sciences Division and its Indian equivalent, the Defence Research and Development Organisation’s Naval Physical and Oceanographic Laboratory.

The cutting edge research will look into using Towed Array Target Motion Analysis to enhance the reliability, efficiency, and interoperability of existing surveillance systems.

Amanda Bessell, the Discipline Leader in DSTG’s Information Sciences Division, mentioned that Target Motion Analysis is a broad term for target tracking algorithms designed to estimate the status of a moving target.

“Target Motion Analysis is essential for keeping platform situational awareness when a passive mode of operation is necessary”, Ms. Bessell stated.

This research project stands out because it uses a towed array-based signal processing system.

Sanjeev Arulampalam, a Senior Researcher at DSTG, described a towed array as a long linear array of hydrophones that is towed behind a submarine or surface ship using a flexible cable.

“The hydrophones collaborate to capture sounds from the underwater environment from different angles”, he mentioned.

The sound signals are processed through a signal processor that analyzes, filters, and detects underwater acoustic signals coming from maritime targets.

The Target Motion Analysis combined with the towed array system aims to handle noise interference and look into potential performance enhancements.

This collaborative project will test out new algorithms, leveraging the strengths and expertise of both nations.

Mr. Arulampalam mentioned, “The project setup will include exchanging ideas, conducting investigation trials, demonstrating algorithms, and analyzing performance”.

As the underwater battlespace evolves, especially with more autonomous vehicles being used, enhancing surveillance capabilities has become a top priority.

“The results from this research program could steer the future algorithmic paths for our undersea combat system’s surveillance tech”, said Suneel Randhawa, Chief of the Information Sciences Division.

By leveraging international partnerships, Defence can tap into a wider array of expertise, infrastructure, and technical data to tackle shared challenges and create innovative technologies.

“We should tap into the brightest minds in innovation, science, and tech to develop new skills, speed up innovation, and enhance our strategic partnerships”, Mr. Randhawa mentioned.
