Referring to fig. 2 another embodiment of the present application provides a microwave radar 100' comprising: base 110 ', first motor 111', bracket 130 ', and antenna assembly 150'. The antenna assembly 150 is mounted on the bracket 130 ' and rotates with the bracket 130 ' relative to the base 110 '. Wherein the antenna assembly 150 ' is movably connected with the support 130 ', and the radiation range of the antenna assembly 150 ' is adjusted by changing the inclination angle of the antenna assembly 150 ' relative to the rotation axis of the support 130 '.
