Laser infrared composite target simulator

The utility model discloses a laser infrared composite target simulator, which is characterized in that a black body emits an infrared radiation signal, the infrared radiation signal passes through a black body diaphragm, then passes through a beam combiner, is projected to an off-axis parabolic mirror, and is converted into parallel light to be output by the off-axis parabolic mirror; laser pulse signals emitted by the laser device are projected to the lens array in parallel through the collimating lens, the lens array divides parallel light emitted by the collimating lens into sub-beams, the sub-beams are then projected to the inclined plane of the reflector, the reflector reflects the sub-beams and then converges the sub-beams to the convergent lens, the convergent lens projects the sub-beams to the diffusion sheet, and the diffusion sheet is used for diffusing the sub-beams. The sub light beams are mutually overlapped on the diffusion sheet to form uniform irradiation light, the irradiation light is proje
