With the development of passive radars,real-time processing ability has become an important factor of the system performance.The exiting processing means are only suitable for low sample rate signals or low-speed targets.When it comes to high sample rate signals(such as digital TV signals)or small high-speed targets real-time processing is difficult to achieve.A real-time implementation of signal processing for passive radars based on the graphic processing unit(GPU)is presented,which can enhance the parall...
