Improving Angle Estimation Accuracy for Millimeter-Wave Radars
Radar systems transmit electromagnetic waves through the air and the objects in the aperture reflect the signal. The reflected signal is captured by the radar to find the position, angle, and velocity of each object. Millimeter-wave (mmWave) radar is a subclass of radar systems that uses millimeter waves to operate. The main advantage of mmWave radars...
