System and method for determining patrol speed |
摘要 |
A system for processing vehicle speed data for a vehicle is provided. The system includes a front antenna assembly of the vehicle generating a front digital signal, and a rear antenna assembly of the vehicle generating a rear digital signal. A fast Fourier transform system converts the front digital signal into front frequency shift data and the rear digital signal into rear frequency shift data. A patrol speed system matches the front frequency shift data and the rear frequency shift data and generates a vehicle speed for the vehicle.
