Abstract
A vehicle radar system includes an antenna module, an RF module, and a signal processor. The antenna module includes at least one transmitting antenna and multiple receiving antennas. The RF module includes a transmitting segment that generates and transmits transmitting waves each carrying a transmitting signal, and a receiving segment that receives reflected waves and incorporates received signal carried by the reflected waves with the transmitting signal into a beat signal. The signal processor performs 2D-FFT on the beat signals to obtain estimated position information of the target object, determines whether a distance value of the estimated position information is greater than a preset distance threshold, and when it is determined that the distance value is greater than the preset distance threshold, perform two-dimensional Multiple Signal Classification (2D-MUSIC) on the estimated position information, so as to obtain an exact distance value and an exact angle value of the target object.
