A projectile detection system, and method of detecting a projectile (for example a bullet), for use on a vehicle () (for example a helicopter), the projectile detection system comprising: a radar antenna array () arranged to transmit and receive microwave signals so as to provide a plurality of detection segments () of a volume of airspace (); one or more processors () arranged to: determine which segments () microwave signals reflected by a projectile () are received from; determine timing information relating to a time order in which the received microwave signals are received; and determine directional information relating to a direction of travel of the projectile () using the determined segments () and the determined timing information; wherein the microwave signals have a frequency between 1 GHz and 30 GHz.

Projectile detection system

A transmitter of a platform is arranged to generate a transmission pulse, which is transmitted to a receiver of another platform and is also arranged to couple its transmission pulse to a digital receiver associated with its platform via an attenuator and a coupler. Another platform performs a similar task. Each digital receiver determines the time separation between its transmission pulse and a received pulse from the other platform. The determined time separation information is shared with the other platform, and each digital receiver then determines a time offset between the time at its platform and the other platform.
