Radar system having vehicle assist function with field of view greater than 160 degrees

A radar system having a vehicle assist function with a field of view greater than 160 degrees, the radar system comprising:

• at least one antenna board, comprising a plurality of antennas disposed thereon and configured to output at least one detection signal to detect at least one obstacle outside a vehicle, and receive at least one reflected signal, which is generated by the at least one detection signal reflected by the at least one obstacle;
• and
• at least one processing unit disposed on the at least one antenna board or electrically connected to the at least one antenna board, and configured to receive and analyze the at least one reflected signal, to determine a distance between the at least one obstacle and the vehicle, wherein the at least one processing unit is able to perform a plurality of vehicle assisting functions, and at least one different warning distance is defined for the plurality of vehicle assisting functions, and when the distance between the at least one obstacle and the vehicle is less than or equal to the at least one different warning distance, the at least one processing unit outputs a warning message to the vehicle, to warn a driver;
• wherein the at least one antenna board comprises a first antenna board and a second antenna board, and the first antenna board and the second antenna board are connected to form an inverted-V shape.
