Is coverage calculation means for calculating coverage based on the radar irradiation capabilities of all radar stations; 105 is coverage display means for displaying coverage of all radar stations; 106 is coverage editing means for editing coverage of radar stations , 107 is a covered area management means for creating a control command for irradiating the edited covered area with radar, 108 is a covered area database (DB) storing the positions of all radar stations and covered area data,
109 is a communication unit that receives a control command from a monitoring station or transmits a radar image; 110 is a radar management unit that controls a monitoring direction from a capture of a radar image and a control command;
Reference numeral 111 denotes a radar transmitting / receiving means for obtaining a radar image, and 112 denotes a wide area network connecting the monitoring station and all the radar stations.

FIG. 2 is an example of the covered area DB 108. The coverage DB 108 has radar data as rows and coverage data for determining the coverage of each radar station as columns. The coverage data includes the radar number, transmission power,
The antenna gain, the wavelength, the coordinates x and the coordinates y representing the position, the start angle and the end angle representing the angle of radar irradiation, and the radar arrival distance, which is the distance that radar radio waves can reach, are stored.

FIG. 3 is an example of a control command transmitted to a single radar station. The control command is transmitted to all the radar stations, and the control command received by the radar station is interpreted by the radar management means 110 in the radar station, and the radar transmission / reception means 111 performs radar irradiation and acquisition of a radar image. In the figure, a control command is represented as three numerical values enclosed by parentheses. The first is the starting angle,
The second end angle and the third are the transmission power. in this case,
The number of control commands is one, indicating that the start angle is 30 degrees, the end angle is 150 degrees, and the transmission power is 80.

FIG. 4 is a flowchart showing the operation of the monitoring station in the first embodiment. The operation of the monitoring station in the first embodiment will be described based on this flowchart. First, the coverage management means 107 reads the coverage data of all the radar stations from the coverage DB 108, stores the read coverage data of each radar station (S101), and the coverage display means 105 stores the coverage data of all the radar stations. Display the covered area (S1
02). Next, the coverage editing unit 105 inputs a change operation from the user (S103). The coverage editing means 106
The input change content of the coverage area is transmitted to the coverage calculation means 104,
The coverage calculation means 104 calculates the radar equation of the pulse radar.

[0017]

(Equation 1)

The coverage area is calculated in accordance with the maximum detection distance based on the above (S105). The maximum detection distance can be obtained by modifying the above radar equation.

[0019]

(Equation 2)

The coverage area can represent a maximum detection distance and a start angle and an end angle at which radar irradiation is performed. The start angle and the end angle for performing the radar irradiation are usually determined by a trade-off with the radar irradiation capability of the radar station, and it is necessary to sacrifice the maximum detection distance when trying to increase the angle for performing the radar irradiation. Conversely, when the radar irradiation angle is narrowed, more radar irradiation can be performed to the same location, and as a result, the maximum detection distance can be extended. The covered area calculated by the covered area calculation means 104 is displayed by the covered area display means 106 (S102). Steps S102 and S105 are repeated until an editing end command is input from the user. When an editing end command is input from the user, the coverage management unit 107 creates a control command for each radar station, and
3 transmits a control command to each radar station (S
106).

In the figure, reference numeral 125 denotes a coverage area when the maximum detection distance is extended by dragging the marker 122 for changing the maximum detection distance. It is a covered area when it is. For example, when the user drags the maximum detection distance changing marker 122 far from the position of the radar station, the maximum detection distance increases.
The coverage editing means 106 notifies the change of the maximum detection distance, which is a user operation, to the coverage calculation means 104, and calculates the coverage according to the changed maximum detection distance. The calculated coverage area is transmitted to the coverage area display means 106 to display the changed coverage area on the screen. When the maximum detection distance is extended as in the case of the covered area 125, the radar irradiation angle is displayed so as to become narrower as the maximum detection distance increases. Conversely, when the maximum detection distance is shortened, the display is made so that the radar irradiation angle increases as the maximum detection distance decreases.

When the user performs an operation to end the editing, the area management unit 107 creates a control command, and the monitoring station communication unit 103 transmits the control command to each radar station. Each radar station transmits the control command received by the communication means 109,
