Full-automatic controllable radar antenna device

The invention discloses a full-automatic controllable radar antenna device, and belongs to the technical field of aerospace. The full-automatic foldable radar antenna comprises a signal enhancement unit, an excited unit, a reflection unit and a linear driving unit. Through sequential movement of two groups of electric push rods, the signal enhancement unit and the reflection unit are driven to stretch out and draw back respectively, and meanwhile, the reflection unit drives the active oscillator group of the excited unit to fold, so that not only can folding of radar antenna oscillators be realized, but also contraction of a main rod can be realized; and the large radar antenna is folded into a size structure which is convenient to transport and store, the length of the main rod is shortened to about half of the length when the main rod is unfolded, and the width of the main rod is only 4-5 times of the diameter of the main rod when the main rod is contracted.
