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 coherent radar detection system ( ) comprises a radar signal transmitter ( ) and a correlation receiver ( ). The transmitter ( ) comprises a waveform generator which generates a signal at an intermediate frequency. The signal is divided into two divided signals by a coupler, and then the divided signals are mixed together in a mixer to generate an output signal which has a wider bandwidth than the intermediate frequency. The bandwidth can be increased further by repeating the coupler/mixer stage. The system generates very wide bandwidth signals coherently, allowing coherent processing in high resolution range gates.
