The utility model discloses millimeter wave human body security inspection equipment, which comprises a first millimeter wave transceiving arc-shaped antenna array, a second millimeter wave transceiving arc-shaped antenna array, a first millimeter wave transceiving module, a second millimeter wave transceiving module, a motion control card, a guide rod, a driving device, a data signal processing module and an upper computer, and the first millimeter wave transceiving arc-shaped antenna array and the second millimeter wave transceiving arc-shaped antenna array are oppositely arranged. Comparedwith a linear antenna array, the millimeter wave transmitting-receiving arc-shaped antenna array structure has the advantages that wave beams are relatively concentrated, image resolution is high, dueto the fact that the opening angle of the arc is large and scanning is carried out along a human body in a moving mode, the cost of the antenna array can be reduced, and high resolution is achieved.
