The radar unit radiates a radar beam, receives the radar beam reflected wave from an object such as raindrops, and performs signal processing of the received signal. The radar unit 2 receives information of the received signal from the radar unit 1 and A receiving function unit for calculating the rainfall intensity value of the observation area; a complement function unit for correcting the rainfall intensity value; and a processing such as conversion of the observation data sent from the complementing function unit into an image format. And a data distribution unit for performing distribution to a terminal or the like (not shown). In general, in a weather radar device, it is preferable to use measurement data at a location close to the ground surface, so that the radar elevation angle of the radar unit 1 is preferably low because accuracy is better. Therefore, in the first embodiment, when observation is performed at a normal radar elevation angle, for example, FIG.
In the case where there is a shielding area by the mountain 5 as shown by the shaded area in (a), the radar unit 1 has a low elevation angle that is shielded by the mountain 5, a higher elevation angle than the above elevation angle, and
Observation at two elevation angles, one with no occluded area,
Observation data 7 including the shielding area 6 as shown in FIG. 2B and observation data 8 not including the shielding area 6 as shown in FIG. The observation data 9 obtained by complementing the observation data 7 with the observation data 8 is obtained. That is, as shown in FIG. 2D, the observation data 9 obtained by the complementing function unit 3 is, for each mesh other than the shielding area 6 of the observation data 7,
The data 7k of each mesh of the observation data 4 is used to complement the data of each mesh of the shielding area 6 with the data 8k of each mesh of the observation data 8. When setting an elevation angle at which the shielding area 6 does not exist,
For example, the topography around the radar unit 1 is input to the supplementary function unit 3 in advance, and an elevation angle at which the shielding area 6 does not exist is set in accordance with the height of the mountain 5.

The reflected wave of the radar beam received by the radar unit 1 is converted into reception level data (observation data) of the reflected wave for each mesh and sent to the reception function unit 2. When there is no occluded area due to the mountains 5 or the like, the observation data is converted into a rainfall intensity value in the reception function unit 2 and then sent to the data distribution unit 3 where the data is subjected to processing such as conversion into an image format. Distributed to terminals and the like outside the figure. Further, as shown in FIG. 2A, when there is a region where the reflection by the mountain 5 cannot be measured, the reflected wave from the region is not received by the radar unit 1 and shown in FIG. 2B. In the observation data 4, a shielded area 6 in which a rainfall intensity value cannot be obtained appears. Therefore, the radar unit 1 sets the observation data 8 at an elevation angle larger than the elevation angle at which the observation data 4 was measured.
Is measured, and the observation data 8 is sent to the complementing function unit 3 via the receiving function unit 2 so that the rainfall intensity value of the shielding area 6 of the observation data 7 is complemented by the observation data 8. . That is, the supplementary function unit 3 uses the topographical data such as the altitude information of the mountains 5 for the occluded area 6 of the observation data 7 and uses a special code (for example, FF (hexadecimal) having a meaning of an unobservable area). )) Is embedded in each mesh of the shielding area 6. Then, as shown in FIG. 2C, from the observation data 8 measured at the large elevation angle, the same azimuth and distance (strictly speaking, The data of the area 8k composed of a mesh having an orthographic projection is extracted to complement the data of the shielding area 6. When complementing, the value of each uppermost mesh having no shielding area 6 is adopted. The complemented observation data 9 (see FIG. 2 (d)) is sent from the complementing function unit 3 to the data distribution unit 4, subjected to processing such as conversion into an image format, and distributed to a terminal or the like (not shown). Is done.

In one radar unit (site) 1, observation data 7 including the occluded area and observation data 8 measured at an elevation angle different from the observation data 7 are measured, and a supplementary function unit 3 is provided. Since the observation data 9 is created by complementing the rainfall intensity value of the shielding area 6 with the above-mentioned observation data 8, the rainfall intensity value can be appropriately complemented. Also, since the rainfall intensity value in the shielded area 6 is appropriately complemented only by the data of the radar unit 1, it is not necessary to perform the level correction of the received signal due to the difference of the radar unit, and the system configuration is not largely changed. Complementation of the shielding area 6 can be performed.

る。In the first embodiment, the description has been made on the assumption that the radar device has one radar unit. However, the radar device may have a plurality of radar units (sites). Further, the rainfall intensity value of the shielding area 6 was complemented by using the received data at the two elevation angles of the radar unit 1, but the radar unit 1 measures observation data at a plurality of elevation angles where the measurement elevation angle is gradually increased. If the occlusion area 6 is complemented by the observation data at a higher elevation angle, the occlusion area 6 becomes narrower. Therefore, the rainfall intensity value of the occlusion area 6 can be finely complemented, and the accuracy of the rainfall intensity value of the occlusion area 6 can be further improved. Can be improved.

In the first embodiment, the rainfall intensity value of the shielding area 6 is complemented by using the observation data 8 at an elevation angle larger than the elevation angle of the observation data 7 having the shielding area 6, but as shown in FIG. Of the observation data 7 at the same elevation angle, the observation data 9 which complements the rainfall intensity value of the shielding area 6 may be created by using the data of any of the left and right areas 7p and 7q of the shielding area 6. . Alternatively, the rainfall intensity value of the shielding area 6 is changed to the area 7p,

Then, it is also possible to select whether to complement the rainfall intensity value of the shielding area 6 with data of different elevation angles or with left and right data, depending on the width of the shielding area 6. Further, if the rainfall intensity value of the shielding area 6 is complemented by a combination of data at different elevation angles and left and right data of the shielding area 6, the accuracy of the rainfall intensity value of the shielding area 6 is further improved.
