Investigations on anti-jamming method for 77GHz automotive millimeter-wave radar

摘要

LSFCW modulation system, presented by this paper based on LFMCW, is more suitable for 77GHz millimeter-wave radar system to identify the target, which takes advantages of the modulation of FSK and LFMCW; and implements multiple target real-time detection ability whether stationary or movement. By means of the chip of ADF4159 from ANALOG DEVICES supporting the modulation of FSK and LFMCW, the fast sawtooth sweep frequency is implemented from 12.765GHz to 12.815GHz; the function of the automotive millimeter-wave radar frequency hopping is realized by means of the frequency of FSK set by properly.
