<p>A radar system including a means for distinguishing signals returned from (i.e., reflected by) objects that are stationary with respect to earth (i.e., 'stationary objects') from signals returned from objects that are moving along with a host vehicle (i.e., the vehicle upon which the radar system is mounted). The system includes a radar antenna having a relatively narrow beam width centered at a 'squint' angle υ. When the antenna is aimed such that the center of the beam is at a squint angle of υ = 60°, the Doppler frequency of signals that are reflected from targets that are stationary along the roadside is significantly higher than the frequency of signals reflected from targets that are in the blind spot to the right-rear of the host vehicle and which are moving along with the host vehicle.</p> |
