The controller at the control tower could only know the location of the aircraft by the pilot's self-reported location report.
In addition, since airport radars are expensive, there are about 15 airports out of 86 airports in Japan, for example, so when an air traffic controller confirms an aircraft coming in the vicinity, it will not be visible at radar-free airports and in the field of view. When it was bad, there was no confirmation means, and when the visibility was good, binoculars were used to detect the direction from the information of the position notification from the aircraft.

[0003]

However, as described above, in the conventional direction detection, the controller has to confirm the position of the aircraft by himself when communicating with the aircraft, and when the visibility is good, I am confirming with the binoculars from the position report information from the aircraft, but if the position report from the aircraft is incorrect, it will be impossible to detect, and if the visibility is bad, I can not check with the binoculars, so it's completely up There was a problem that it would be in the state of.

Further, even if a direction detector is installed in the control tower to detect the direction, it is not immediately responsive to confirm the scale of the direction search for each call, and the scale is to be seen for each direction. There was a problem in that there was complexity in moving the viewpoint.

Next, the operation of this embodiment will be described. First, the radio wave 11 transmitted from the aircraft 10 is received by the wireless device 13 via the antenna 12, and is also received by the direction finder 14. Then, the wireless device 13 converts the received radio wave 11 into an audio signal and outputs it, and the direction finder 14 detects the direction in which the received radio wave 11 is emitted and outputs its angle information.

A voice signal from the wireless device 13 and angle information from the direction finder 14 are input to the voice output processing unit 15, and the voice output processing unit 15 is based on the input angle information. , The target speaker is selected from the speakers 20 to 23 so that the audio signal is output from the direction of the angle information, and the audio signal is output from the selected speaker.

Next, a specific example of the voice output processing section 15 will be described. FIG. 3 is a block diagram showing an example of the audio output processing unit 15 of this embodiment. In the figure, 40-4
Reference numeral 3 is a speaker for transmitting an audio signal from the radio 13 to the speakers 20 to 23.
The audio processing units 40 to 43 are provided to correspond to the speakers 20 to 23, respectively.
It is designed to control the on / off of the output to 23 and the output level.

The angle information 44 is inputted with the angle information from the direction finder 14, and based on the angle information, the voice processing units 40-4.

In the example of the audio output processing unit 15, the controller controls the output of audio signals from the speakers 20 to 23 arranged as shown in FIG. 2 based on the angle information from the direction finder 14. The audio signal can be heard from the direction indicated by the angle information 31.

For example, when the angle information indicates the east direction, an audio signal is output from the east speaker 20, and when the angle information indicates the southeast direction, the east speaker 20 and the south direction are output. The speaker 21 outputs a sound signal of the same volume. Further, when the angle information is south-southeast direction, the speaker 20 in the east direction and the speaker 21 in the south direction output sound signals having different volumes, and the controller 31 uses the speaker. The direction in which the aircraft 10 is coming can be known only by listening to the audio signals output from 20 to 23.
