This paper presents a fully integrated 77GHz FMCW radar system in 65nm CMOS. The FMCW radar transmits a continuous wave which is triangularly modulated in frequency and receives the wave reflected from objects. As can be illustrated in Fig. 11.2.1, for a moving target, the received frequency would be shifted (i.e. Doppler shift), resulting in two different offset frequencies f+ and f- for the falling and rising ramps. Denoting the modulation range and period as B and Tm, respectively, we can derive the distance Rand the relative velocity V R as listed in Fig. 11.2.1, where fc represents the center frequency and c the speed of light. ©2010 IEEE. |
