Claims

[Scope of utility model registration request]

In a radome testing device that can measure beam deviation, which is one of the performance characteristics of a radome, the radome uses a rotating table that rotates the radome and outputs the rotation angle, a rotating table controller that controls the rotating table, and a rotating table that rotates the radome and outputs the rotation angle. a microwave transmitter that emits RF waves at a frequency of a receiver that outputs a proportional signal, a servo amplifier that inputs a signal of the difference between the electrical boresight and the mechanical boresight, and a difference signal between the electrical boresight and the mechanical boresight that is generated by the output of the servo amplifier. a primary horn that has a null tracking function to zero, outputs angle information, and radiates the RF waves of the microwave transmitter; and a reflector that completely converts the RF waves emitted by the primary horn into a defensive wave. a data controller that obtains angular information from the primary horn and the rotary table and outputs the amount of beam deviation of the radome, and outputs radome characteristics from the output of the receiver and the angular information of the rotary table; A radome testing device comprising: a beam deflection recorder for recording the radome characteristics; and a pattern recorder for recording the radome characteristics.
