Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a radio wave direction finding control device that supplies direction data obtained by a direction finding device as calculation data to a computer that performs calculation detection of a radio wave emission source. It is.

(Prior Art) Radio wave direction detection systems for detecting radio wave emission sources such as radio wave emission bases, illegal radio wave emission sources, and radio wave emission vehicles are well known.

Generally, this radio wave direction finding system includes a plurality of direction finding devices 1, a radio wave direction finding control device 2, and a computer 3, as shown in FIG. The direction finding device 1 has an antenna that can rotate within an azimuth range of 36σ, and detects the direction in which the reception signal of the antenna is maximum as the azimuth data of the radio wave emission source. Normally, the direction in which this received signal is maximum is unstable and is not fixed in a fixed direction, but fluctuates within a certain minute width. The direction finding device 1 further detects this varying minute width as precision data indicating the precision of the direction data. The radio wave direction finding control device 2 collects direction data and accuracy data from each direction finding device 1 and supplies predetermined direction data to the computer 3. The computer 3 performs necessary calculations using the azimuth data and calculates and detects the position of the radio wave emission source.

Generally, in order to accurately determine the location of a radio wave emission source by calculating the position, it is necessary to use and process a large amount of data, but on the other hand, there is the problem that computer processing takes a long time.

Therefore, in recent years, from among the large number of azimuth data supplied from the directional finding device 1, a necessary number of azimuth data is uniquely selected so that the calculation accuracy is not reduced and the calculation process is sufficiently shortened. A selection device, for example, a selection device that sequentially selects a required number of data from the top of the accuracy data, is provided in the radio direction finding control device 2, and the radio direction finding control device 2 is connected to the computer 3.
The amount of data to be supplied to the computer is selected to reduce computer processing time.

(Problem to be Solved by the Invention) However, as described above, in the method of uniquely selecting orientation data, even error data is selected as calculation processing data as long as accuracy data is at the top. In such a case, there is a problem that a large error occurs in the calculation result and it is not possible to accurately determine the radio wave emission source.

The present invention has been made in order to solve the above-mentioned conventional problems, and its purpose is to reliably eliminate error data from being selected as computer calculation data, and to calculate accurate radio wave emission sources in a short time. It is an object of the present invention to provide a radio wave direction finding control device that makes it possible to obtain information using processing time.

(Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows. That is, the present invention provides a radio direction finding control device that collects direction data from a plurality of direction finding devices and supplies the collected direction data to a computer for radio wave emission source detection calculation. A radio wave direction finding control equipped with a display device that displays azimuth data on the same screen, and a data selection device that selects and outputs azimuth data used for computer calculations from a plurality of azimuth data displayed on the display device. It is a device.

(Function) In the present invention having the above configuration, the direction data supplied from the plurality of direction finding devices is displayed in a desired manner, for example, a graphic form, on the same screen of the display device. Therefore, by observing this display screen, the operator can distinguish error data from other error-free data at a glance. Next, the operator operates the data selection device to select a predetermined number of appropriate data from the azimuth data excluding error data, and outputs the selected azimuth data to the computer. Therefore, the computer can accurately determine the position of the radio wave emission source by using suitable azimuth data that does not include this error data through quick calculation processing.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. It should be noted that the radio wave direction finding control device of this embodiment is used in the same system as the radio wave direction finding system shown in FIG. .

FIG. 1 shows a block diagram showing details of the radio wave direction finding control device 2 of the present invention. The radio wave direction finding control device 2 of this embodiment includes a display device 4 that displays direction data from the direction finding device 1 as a graphic image, and this display device 4.

The display device 4 includes a transmission data processing section 6, a logic processing section 7, and a display section 8, while the data selection device consists of the logic processing section 7, a selection operation section 9, and a transmission data processing section 10. Become. The transmission data processing section 6 of the display device 4 collects azimuth data and accuracy data from each direction finding device 1 and outputs the collected data to the logic processing section 7. The logic processing section 7 stores the azimuth data, creates an azimuth signal for display in correspondence with each azimuth of the azimuth data, and processes the coloring of this azimuth signal and the azimuth data based on accuracy data. For example, the direction data with high accuracy is blue, and the data with low accuracy is red, so that the color changes from cold to warm as the data goes from high accuracy to data with low accuracy (and vice versa, from warm to cold). ) Perform coloring. In this case, it is also possible to display changes in the precision of the orientation data not by changes in hue but by changes in brightness. The colored orientation data is output to the display section 8. As shown in FIG.
Direction data (direction signal) and accuracy data from i are displayed graphically. That is, the direction of each direction data is represented by the direction of straight lines 12, 13, 14, 15 and 16 drawn starting from point 11 indicating the position of each direction finding device R1, and the accuracy of the accuracy data is expressed by the direction of straight line 12 .13
．． 14.15 and the same 1G colors.

On the other hand, the selection operation section 9 is provided with selection buttons for selecting the orientation data displayed on the display section 8, and the operator observes the screen of the display section 8 and operates the selection buttons to select the direction data displayed on the display section 8. Select a predetermined number of azimuth data to be used for data calculation. On the other hand, a selection signal is generated by operating this selection button, and this selection signal is supplied to the logic processing section 7.

The logic processing section 7 reads out the azimuth data selected by this selection signal and sends this read data to the transmission data processing section 10.

The transmission data processing section 10 further sends this azimuth data to the computer 3. As a result, the radio wave emission source is detected by the computer 3 as described above.

As described above, according to this embodiment, the orientation data used for calculations by the computer 3 can be selected by visually comprehensively determining the direction and color of the straight line in the graphic image shown in FIG. , and when making this selection, for example, the second
Error data as shown by the straight line 16 in the figure can be distinguished from other error-free data at a glance, and as a result of being excluded from the operator's selections, only suitable azimuth data with few errors can be selected. This makes it possible to quickly and accurately calculate and detect the position of the radio wave emission source.
