WebOff-the-shelf automotive radars operate with a sequence of linear frequency-modulated continuous-wave (FMCW) signals to simultaneously measure range, angle, and velocity. According to regulations, automotive radar is allowed to use two frequency bands in millimetre waves: 24 GHz (24–24.25 GHz) and 77 GHz (77–79 GHz). WebFollowing are the drawbacks or disadvantages of millimeter wave (mmwave) radar: It is vulnerable to atmosphere and other meteorological parameters. Hence it does not provide accurate distance measurements of nearby objects. This weakens threat identification process. It is over sensitive and often creates false alarm even in the absence of real ...
