There is a requirement to be able to stop vehicles for law enforcement or security purposes. This may be achieved by applying a lethal solution but it may not be the most desirable outcome and can result in injuries to bystanders, law enforcement officers and collateral damage.
One non-lethal solution is to deploy a mechanical device in the path of a target vehicle to damage its tyres but this can be dangerous for personnel and difficult to position.
In another solution, a high power broadband microwave/VHF source may be employed to direct an electromagnetic pulse at a target vehicle but due to the broadband nature of the signal, which may have little directivity, this could cause damage to vehicle and danger to occupants and bystanders, for example, people with pacemakers being particularly vulnerable.
