The invention discloses a vehicle-mounted active phased array radar, which is characterized in that a radar module can rotate under the action of a rotary scanning driving module, and the pitching angle of the radar module relative to the horizontal plane can be greatly adjusted; the radar module can slightly adjust the pitching angle of the radar module relative to the horizontal plane under theaction of the cyclic scanning driving module, and can periodically make reciprocating side-sway actions, so that a target object can be accurately monitored in a small range, the detection range of the radar module is expanded, and the detection efficiency of the radar module is improved. According to the invention, an independent heat dissipation structure is not arranged, the bearing plate of the radar module is arranged to be of the cavity structure, the antenna units are evenly arranged on the surface of the bearing plate, the ventilation holes communicating with the cavity structure are formed right opposite to t
