Millimeter wave radar and unmanned aerial vehicle

The invention discloses a millimeter wave radar and an unmanned aerial vehicle. The millimeter wave radar comprises a radar chip, a transmitting antenna array and a receiving antenna array. The radar chip is provided with a transmitting end and a receiving end; the transmitting antenna array is connected with the transmitting end of the radar chip. The transmitting antenna array comprises two first comb-shaped antennas and two first series-fed antennas. The receiving antenna array is connected with the receiving end of the radar chip. The receiving antenna array comprises two second comb-shaped antennas and two second series-fed antennas. Wherein the two first comb-shaped antennas, the two second comb-shaped antennas and the second series-fed antenna form a first virtual sparse array on a pitching plane, and the first comb-shaped antenna, the two first series-fed antennas and the two second series-fed antennas form a second virtual sparse array on a horizontal plane. The virtual aperture of the second virtual
