The invention discloses a phased array radar detection system, which can avoid the use of a rotating device and ensure the working stability of a radar through the arrangement of a plurality of phased array antennas. Because the dielectric element is self-supporting, even if the antenna vibrates or impacts during operation, the dielectric element can be locked at a proper position in each waveguide; a dielectric element partially fills each individual waveguide and includes features for providing impedance matching, enhancing the operating frequency range, facilitating propagation of signals between the waveguide horn and the individual waveguide; due to the arrangement of the first slotted hole and the third slotted hole, the dielectric element is easier to be compressed to generate tiny deformation in the plug-in installation process, and plug-in operation is facilitated; the arrangement of the second slotted hole and the fourth slotted hole is beneficial to reducing the weight of the dielectric element and
