| Abstract: | In recent years,automobile anti-collision radar system is being studied and used widely to satisfy the need of the safety of driving.The signal processing technique of wavelet is put forward to serve the automobile anti-collision radar system with millimeter-wave radar technology in this paper.The application of wavelet technique can offer convenience to decompose signals according to frequency.It also can help distinguish multi-targets and remove validly the disturb and virtual warning of signal which is caused by road,fence,trees and buildings. |
