A vehicle radar device includes a first antenna unit, a second antenna unit, at least one computing unit, at least one circuit board and a housing. The first antenna unit includes at least one first receiving antenna. The second antenna unit includes at least two second receiving antennas. The at least two second receiving antennas are in at least two antenna types, respectively. The first antenna unit and the second antenna unit are communicatively connected to the computing unit. The circuit board includes a first board portion and a second board portion. The first antenna unit is in a circuit board type and disposed on the first board portion. The second antenna unit is in a circuit board type and disposed on the second board portion. The first antenna unit, the second antenna unit, the computing unit and the circuit board are all disposed in the housing, which includes a bottom portion. When a specific condition is satisfied, it is advantageous in providing a larger detection range and reducing the range
