Performance comparison between automobile driverless 24GHz anti-collision radar and 77GHz millimeter wave radar:
1. With different frequencies, the wavelength of 24GHz millimeter wave radar is greater than 10cm. Strictly speaking, 24GHz millimeter wave radar belongs to centimeter wave radar
2. 77GHz millimeter wave radar meets both high transmission power and wide working bandwidth, so that it can achieve long-range detection and high-range resolution at the same time
3. 77 GHz millimeter wave radar has significant advantages in object resolution, velocity measurement and ranging accuracy
4. 77GHz millimeter wave radar is smaller, and its wavelength is less than 1 / 3 of 24GHz. Therefore, the area of transceiver antenna is greatly reduced and the size of radar is reduced
At present, Rogers 3003g2 + Shengyi 1000-2m is used for 77GHz millimeter wave radar PCB produced by QUANHONG, and the line tolerance is + / - 0.02mm, which can be mature and mass produced
