[0041] In this embodiment, the darkroom 3 is a relatively enclosed environment with only one door opened. High-density fine copper wire meshes are arranged on the side walls, top wall and bottom plate of the darkroom 3, and the high-density fine copper wire meshes are all well grounded to achieve the effect of electromagnetic shielding through the high-density fine copper wire meshes. Absorbing materials 4 are laid on the high-density fine copper wire meshes ( Figure 1 only part of the absorbing materials 4 are shown in

[0042] In this embodiment, as Figure 3 shown, the three-axis test turntable 12 can control the pitching, rotation and yaw of the anti-radiation seeker. As Figure 4As shown in the figure, several fixed transmitter antenna modules 21 and sliding transmitter antenna modules 22 can radiate signals simultaneously or at different times. During multi-signal source testing, any one of the fixed transmitter antenna modules 21 or the transmitter antenna module 22 is designated as the target signal source.

The laid electromagnetic wave absorbing material 4 reduces the influence generated by the reflection of electromagnetic waves by the underlying steel frame. The main equipment lifting bracket 13 is used to lift the measurement and control three-axis turntable and the equipment to be measured to the same height as the upper end face of the equipment carrier 11 to facilitate the installation and transfer of the equipment. The auxiliary equipment lifting bracket 14 is used to lift the anti-radiation seeker equipment to be measured to the height of the three-axis test turntable 12 to facilitate the installation of the equipment on the three-axis test turntable 12.

By setting two groups of sliding transmitter antenna modules 2, the response speed of the seeker to moving targets is tested. The three-axis test turntable 12 guides the test system to feed back the target azimuth data to which the seeker turns to the three-axis test turntable 12 for quick pointing, and the infrared laser on the three-axis test turntable 12 more directly feeds back the accuracy of the equipment's direction finding.
