Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radar information processing apparatus for processing radar information and displaying the position of a target aircraft in an air traffic control air space or a terminal control air space on a radar display device.

[0002]

2. Description of the Related Art Conventionally, there are the following two types of radar information processing devices of this type depending on the difference in display method of radar information on a radar display device.

(A) One is to perform track correlation processing on the basis of radar information from a single radar to create a track of each target aircraft, and to divide each in a circular radar coverage area 100 as shown in FIG. Area (area from the radar antenna to each fixed direction)
By sequentially updating the displayed contents 101, 102, ... In synchronization with the radar rotation in the order of display time 1, display time 2, ..., The created track is almost synchronized with the input time of radar information. Information processing device for displaying on a radar display device.

(B) The other one is to perform track correlation processing and smoothing processing on the basis of radar information from a plurality of radars to create a track of each target aircraft, and to cover a plurality of radars as shown in FIG. Each divided area (rectangular area vertically divided into a predetermined size) 201, 20 in the display area 200 that covers the area
2, ... A radar information processing apparatus for displaying the created track on a radar display device by sequentially updating the displayed contents asynchronously with the radar rotation at regular time intervals.

[0005]

Among the conventional radar information processing apparatuses described above, the radar information processing apparatus (A) is
Since the display contents are sequentially updated in synchronization with the radar rotation,
The time from receiving the radar information to updating the display content of the radar display device is short. Therefore, it is suitable for terminal control and the like that requires prompt control.

However, since the air space covered by the radar coverage of a single radar is not so wide, it is not suitable for air traffic control or the like which requires control over a relatively wide air space.

Further, when the radar coverage by the display system as shown in FIG. 5 is displayed on the same radar display device for a plurality of radars as shown in FIG. 7, the covered airspace is expanded, but each radar coverage 301 , 302, and 303 are displayed and updated in synchronization with separate radar rotations, the display update timings of the areas 304 and 305 in which a plurality of radar coverage areas overlap are not constant. For this reason, there is a risk of transmitting incorrect information to the controller. Therefore, such a display method cannot be generally adopted.

On the other hand, the radar information processing device (B) is
Different from the radar information processing device of (A), each of the divided areas 201, 2 of the display area 200 covering a plurality of radar coverage areas
02, ... Is updated at a constant display update timing, so that a relatively wide area can be uniformly displayed.
However, since the display is updated every fixed time asynchronously with the input time of the radar information, it takes a long time from the reception of the radar information to the update of the display content of the radar display device. Therefore, it is suitable for air traffic control, but cannot be used for terminal control because the display update delay is unacceptable.

As described above, the conventional radar information processing apparatus is
There is a problem that it can only be used for either air traffic control or terminal control.

Therefore, the object of the present invention is to arbitrarily select the display system as shown in FIG. 5 (hereinafter referred to as the first display system) or the display system as shown in FIG. 6 (hereinafter referred to as the second display system). Therefore, it is an object of the present invention to provide a radar information processing apparatus which can be commonly used for different control such as air traffic control and terminal control.
