| description | In recent years, frequency-modulated continuous-wave (FMCW) radars have been widely used in the automotive field to measure the relative distance and speed of external targets. To address the problems of poor sensitivity, narrow measurement range, and poor stability of current FMCW radar systems, a high-order all-digital phase-locked loop (ADPLL) based on a fast-integration structure was designed for the FMCW radar. According to the measurement principle of the distance and velocity of objects using radar, the loop structure was designed using integrated circuit chip technology. A Z-domain model of the loop system was built using MATLAB software, and stability analyses and comparisons were performed. The loop program was written using the hardware description language and simulated using the MODELSIM software. Simulation results were combined to verify the accuracy of the hardware design. The experimental results showed that the ADPLL effectively increased the phase-locking frequency, expanded the frequency modulation range by nearly ten times, reduced the system delay by approximately 36%, and improved system stability. |
