Embodiment Construction
[0033] A passive millimeter-wave imaging security inspection device, comprising: a one-dimensional focal plane array 1, a reflector 3, a display and control subsystem 4, a signal processor 5, an internal calibration combination 6, a reflector rotation mechanism 7, a dielectric panel 8, and a frame 9 and the detection platform 11, further comprising: an ellipsoid reflective surface 2 and an external calibration combination 10. The one-dimensional focal plane array 1 includes: receiving antennas 1-1-i, where i is 1-N, and radiometers 1-1-i, where i is 1-N. The internal calibration combination 6 includes: a normal temperature calibration source 6-3, a high temperature calibration source 6-4, a rotating motor 6-1, and a mechanical connector 6-2. The normal temperature calibration source includes wave-absorbing material A6-9, metal structure A6-10, and temperature sensor A6-11. The high-temperature calibration source includes a wave-absorbing material B6-5, a metal structure B6-6,...
