Radio wave propagation environment reproduction system and radio wave propagation environment reproduction method

A radio wave propagation environment reproduction system comprising:

• a transmitter to transmit radio waves in a predetermined direction in a reverberation chamber;
• a reflector to reflect the radio waves transmitted by the transmitter;
• an installation angle controller to control an installation angle of the reflector by outputting a control signal to the reflector;
• a reflected power change RIS to change the radio waves reflected by the reflector to power according to a control signal and reflects the power;
• a reflected power controller to control the power of the radio waves reflected by the reflected power change RIS by outputting a control signal to the reflected power change RIS;
• a direction-of-arrival estimator to estimate a direction of arrival of the radio waves reflected by the reflected power change RIS at a predetermined position in the reverberation chamber;
• and
• a control server to control the installation angle controller and the reflected power controller on the basis of the direction of arrival of the radio waves estimated by the direction-of-arrival estimator.

A radio wave propagation environment reproduction method comprising:

• controlling an installation angle of a reflection angle change RIS to reflect radio waves transmitted by a transmitter in a predetermined direction in a reverberation chamber at an angle according to a control signal;
• controlling a reflection angle of the radio waves reflected by the reflection angle change RIS according to a control signal;
• estimating a direction of arrival of the radio waves reflected by the reflection angle change RIS at a predetermined position in the reverberation chamber;
• and
• controlling the installation angle and the reflection angle of the reflection angle change RIS on the basis of the estimated direction of arrival of the radio waves.
