Abstract |
Most of the modern systems use complex analysis and processing of output signals by using expensive digital signal processors (DSP). In the present work, a novel method of zero-crossing detector (ZCD) algorithm for frequency calculation is implemented. The output of the Doppler RADAR which is a sine wave is band-limited, amplified and then fed to a ZCD. The output of the ZCD a Digital signal can be directly fed to the microcontrollers counter (T0 or T1) without the use of an ADC. The microcontroller calculates and displays the speed. The algorithm proposed for vehicular speed detection is a good platform than the other algorithms which are complex and Costly. | |||||||||
