Abstract: A simulation system includes a driving simulator, a radio propagation simulator, and an application simulator. The driving simulator generates a driving scenario representing at least behavior of a vehicle. The radio propagation simulator calculates a propagation parameter representing a radio wave to be received by one or more antennas installed in the vehicle. The propagation parameter is calculated on the basis of antenna performance of the one or more antennas and a position of the vehicle. The position of the vehicle is indicated by the driving scenario generated by the driving simulator. The application simulator simulates operation of an application serving to control operation of the vehicle. The operation of the application is simulated by using at least information based on the propagation parameter.

Abstract: An antenna device is mounted on a vehicle and performs vehicle-to-vehicle and road-to-vehicle communications using a plurality of communicators including antennas. The antenna device includes one or more hardware processors coupled to one or more memories, and configured to function as, communication control units, a vehicle state detection unit, and operation control units. Communication control units are each provided in one of the plurality of communicators and control transmission/reception operations of the antennas connected to the communicators. A vehicle state detection unit detects a state of the vehicle and operation states of the communication control units. Operation control units are each provided in one of the plurality of communicators and control the operation states of the communication control units according to the state of the vehicle detected by the vehicle state detection unit and the operation states of the communication control units, for each of the plurality of communicators.

Abstract: A measurement apparatus outputs a correction result obtained by performing correction on a target radio wave received by a measurement mechanism which includes an antenna for receiving the target radio wave and a support member for supporting the antenna. The measurement apparatus acquires a first received radio wave phase being a phase of the target radio wave received by the antenna from a target. The measurement apparatus calculates an ideal phase of the target radio wave at each position of the antenna. The measurement apparatus acquires a second received radio wave phase being a phase of the target radio wave received by the antenna from the target at each position of the antenna. The measurement apparatus performs correction based on distortion of the support member, which is calculated from a difference between the ideal phase and the second received radio wave phase.
