Problems solved by technology

[0003] The target simulation and interference devices developed in the past mainly focus on single dynamic target and static interference simulation, which cannot realize the simultaneous dynamic simulation of the target and interference source, and the field of view is small
However, the general dynamic simulation interference device simulates a single interference source scene, and cannot simultaneously simulate the time discontinuity and space discontinuity of interference light, nor can it meet the test requirements of the comprehensive influence of multiple interference sources in a complex space environment.
The previous target and compound interference devices were large in size and could not meet the space requirements of the laboratory
