| Abstract: | A new design with master-slave processor is adopted in the system of millimeter wave automotive anti-collusion radar based on DSP. The slave processor AT89C51 realizes man-machine interactive function, display and alarming control. The sound and light alarming unit is controlled by AT89C51 when the distance obtained by master processor DSP exceeds the threshold. The signal in time domain is transformed into frequency domain through fast Fourier transform (FFT), and the result can be obtained from sampling. |
