A Scottish postgraduate engineer has apparently made a discovery that could make it easier for driverless vehicles to communicate in cities.

The Scotsman newspaper reports PhD student Euan Ward has developed an algorithm that could transform the capability of driverless cars, through the addition of radar technology that is protected from radio frequency interference.

It says this could pave the way for the widespread use of fully autonomous vehicles in built-up or busy areas.

At present, self-driving cars and unmanned aerial vehicles rely on conventional sensors to avoid collisions, but these can only detect threats within a certain radius.

The report says with the support of Leonardo, Euan has developed new techniques to protect modern radar systems against harmful interference. This could allow low-cost radar systems to maintain their performance when operating in close proximity to one another.
