As shown in fig. 1 to 4, the corner reflecting device according to the embodiment of the present invention includes a base 1, a corner reflector 2, a direction angle measuring ring 3, and an adjusting mechanism 4. The direction angle measuring ring 3 is arranged on the base 1, the direction angle measuring ring 3 is provided with a through hole 31, the direction angle measuring ring 3 is provided with 360-degree annular scales, and the minimum scale of the direction angle measuring ring 3 is 1 degree.

It can be understood that, when the azimuth angle of the corner reflector 2 is adjusted, the corner reflector 2 at the other end of the adjusting mechanism 4 can be driven to rotate by adjusting one end of the adjusting mechanism 4 to rotate in the through hole 31 of the direction angle measuring ring 3, thereby realizing the adjustment of the azimuth angle of the corner reflector 2. Because the direction angle measuring ring 3 is provided with 360-degree annular scales, the rotating angle of the adjusting mechanism 4 can be determined when one end of the adjusting mechanism 4 is rotated, the rotating angle of the corner reflector 2 can be determined according to the rotating angle of the adjusting mechanism 4, and finally the azimuth angle of the corner reflector 2 after the rotation is finished is determined. After the azimuth angle of the corner reflector 2 is adjusted, the end of the adjusting mechanism 4 matched with the through hole 31 is fixed on the base 1, and the pitch angle of the corner reflector 2 can be adjusted by adjusting the adjusting assembly 43. In the process of adjusting the pitch angle, the angle measuring part 5 can measure the angle between the corner reflector 2 and the base 1 in real time, so that the pitch angle of the corner reflector 2 after adjustment is determined.

In addition, the minimum scales of the direction angle measuring ring 3 and the angle measuring piece 5 are both 1 degree, so that the angle adjustment of the corner reflector 2 has higher precision, and the phenomenon that the radar signal is difficult to reach the maximum scattering cross section of the corner reflector 2 due to precision errors is reduced.

In some embodiments, as shown in fig. 1 and 2, the corner reflector 2 includes a bottom plate 21 and side plates 22. The number of the side plates 22 is two, the two side plates 22 are respectively connected with the two side edges of the bottom plate 21 through first connecting plates 23, and the two side plates 22 are connected through second connecting plates 24. Specifically, in the present embodiment, the first connecting plate 23 and the second connecting plate 24 are both reinforcing angle irons. The bottom plate 21 and the two side plates 22 are isosceles right-angle triangular plates, and the length of the two right-angle sides is 1200 mm.

In some embodiments, as shown in fig. 1 and 2, the adjustment mechanism 4 includes a rotating disk 41 and a connecting frame 42. The rotating disk 41 is rotatably fitted in the through hole 31. The number of the link frames 42 is three, and one end of each link frame 42 is connected to the rotating disc 41, and the other end is connected to an adjusting member 43, and the adjusting member 43 is rotatably connected to the corner reflector 2.

It can be understood that, when the rotating disc 41 is rotated, the three connecting frames 42 arranged thereon are driven to rotate, the three connecting frames 42 respectively drive the adjusting assemblies 43 connected thereto to rotate, and the three adjusting assemblies 43 further drive the corner reflector 2 rotatably connected thereto to rotate, thereby realizing the adjustment of the azimuth angle of the corner reflector 2. The arrangement of the three connecting frames 42 and the adjusting assembly 43 can stably support the corner reflector 2, improve the stability of the corner reflector device, facilitate the adjustment of the pitch angle of the corner reflector 2, and reduce the possibility that the corner reflector 2 is separated from the base 1 in a wild environment. Furthermore, the rotating disk 41 includes a rotating body 411 and a fixed pointer 412 fixedly connected to the rotating body 411, and when the rotating disk 41 is rotated, the azimuth angle of the corner reflector 2 can be obtained through the rotating pointer 52 and the annular scale on the direction angle measuring ring 3.

Specifically, the upper and lower surfaces of the connecting frame 42 are provided with locking nuts for locking the adjusting members 431, the adjusting members 431 are ball-head support rods, the first connecting plate 23 and the second connecting plate 24 are both provided with fixing members 432, and the ball heads of the ball-head support rods are rotatably matched with the fixing members 432. It can be understood that, when adjusting the pitch angle of the corner reflector 2, the locking nut is loosened, and the three adjusting members 431 are slid to adjust the included angle between the bottom plate 21 and the side plate 22 and the horizontal plane, and the angle value of the pitch angle of the corner reflector 2 is obtained through the angle measuring member 5, and when the angle value of the pitch angle reaches a specified value, the adjusting members 431 are locked through the locking nut, and then the adjustment of the pitch angle of the corner reflector 2 is completed. Since the other ends of the three adjusting members 431 are rotatably connected to the two first connection plates 23 and the second connection plate 24, respectively, the three adjusting members 431 can stably support the corner reflector 2, and the stability of the corner reflecting device is improved.

In some embodiments, as shown in fig. 1 and 2, the number of the angle measuring parts 5 is two, the angle measuring parts 5 are semicircular dials, the scales on the two ends of the semicircular dial are 90 degrees, the scale on the center of the semicircular dial is 0 degree, each semicircular dial is respectively arranged corresponding to the connection position of the first connecting plate 23 and the adjusting part 431, and the tangent lines passing through the two end points of the semicircular dial are perpendicular to the first connecting plate 23.

Specifically, in the present embodiment, the upper surface of the base 1 and the connecting frame 42 are both horizontally disposed, and the adjusting members 431 are both vertically disposed in the up-down direction. It will be appreciated that in the initial state, the base plate 21 of the corner reflector 2 and the first connecting plate 23 are both horizontally disposed, since the tangents passing through both end points of the semicircular scale are perpendicular to the first connecting plate 23, and the central scale of the semicircular scale is set to 0 °, i.e. the angle between the angle measuring piece 5 and the base 1 is illustrated to be 0 °. In addition, because the scales at the two ends of the semicircular dial are 90 degrees, when the pitch angle of the corner reflector 2 is adjusted, no matter whether the corner reflector 2 rotates towards the direction close to the base 1 or the direction far away from the base 1, an operator can directly determine the angle of the corner reflector 2 relative to the pitch angle of the base 1 by reading the reading on the angle measuring piece 5, and the complicated steps of measurement and conversion are avoided. Through the structure, the operator can quickly obtain the pitch angle of the corner reflector 2 through the angle measuring piece 5, so that the adjusting efficiency of the operator is improved.

In some embodiments, as shown in fig. 1, 2 and 3, the angle measuring part 5 further includes a rotating pointer 52, the rotating pointer 52 is rotatably connected to the center point of the two end points of the semicircular scale, and the rotating pointer 52 is vertically disposed in the up-down direction.

Specifically, the angle measuring part 5 includes a measuring body 51 and a rotating pointer 52, and the scale of the angle measuring part 5 is provided on the measuring body 51. It will be understood that the rotating hands 52 can be perpendicular to the horizontal plane under their own weight, the rotating hands 52 pointing at 0 ° of the angle measuring member 5 when the bottom plate 21 and the first connecting plate 23 of the corner reflector 2 are horizontally arranged; when the operator adjusts the corner reflector 2, the scale on the angle measuring member 5 to which the rotating pointer 52 is directed is the angle between the bottom plate 21 and the first connecting plate 23 of the corner reflector 2 and the horizontal plane. The setting of the rotating pointer 52 enables the operator to quickly acquire the pitch angle of the corner reflector 2, improving the adjustment efficiency of the operator.

In some embodiments, the direction angle measuring ring 3 is provided with four connecting bolts 6 along the cross direction, the direction angle measuring ring 3 is connected with the base 1 through the four connecting bolts 6, and the 0 ° position of the annular scale is located in the north direction.

Specifically, the four connecting bolts 6 are respectively arranged at the positions of the directions of 0 °, 90 °, 180 ° and 270 ° of the annular scale, and the four connecting bolts 6 can guide the installation of the direction angle measuring ring 3. When the direction angle measuring ring 3 is arranged on the base 1, the 0-degree position of the annular scale is positioned in the north direction, namely 180-degree position of the annular scale is positioned in the south direction, 90-degree position is positioned in the east direction, and 270-degree position is positioned in the west direction. Through the arrangement, the specific azimuth of the azimuth angle of the corner reflector 2 can be read in real time when the azimuth angle of the corner reflector 2 is adjusted, the complicated conversion process is avoided, and therefore the adjusting efficiency of operators is improved.

In some embodiments, as shown in fig. 1 and 2, a silt-proof hole 100 is provided at the joint of the bottom plate 21 and the two side plates 22. It can be understood that, since the corner reflector 2 is generally installed in the open air in the field, the environment is complex, so that external impurities such as rain water, fallen leaves, etc. are deposited on the bottom plate 21 of the corner reflector 2, thereby affecting the accurate identification of the corner reflector 2 on the SAR image. In order to reduce the above phenomenon, a silt preventing hole 100 is provided at a junction of the bottom plate 21 and the side plate 22 so that impurities such as rainwater and fallen leaves can be smoothly discharged from the corner reflector 2, thereby improving the accuracy of the corner reflector 2. In addition, the air flow in the field environment also easily causes the swinging of the corner reflector 2, and the anti-silt hole 100 enables the air to pass through the corner reflector 2 when flowing, thereby reducing the influence of the air flow on the corner reflector 2 and prolonging the service life of the corner reflector 2. Specifically, since the bottom plate 21 and the two side plates 22 are connected at the tops of the two right-angled sides, the tops of the right-angled sides of the three isosceles right-angled triangular plates, namely the bottom plate 21 and the two side plates 22, are cut off by 180mm, so that the bottom plate 21 and the two side plates 22 form the silt preventing hole 100 at the positions.

It can be understood that, in order to enhance the firmness of the base 1, the base 1 in this embodiment is a reinforced concrete member, and the reinforced concrete member is a reinforced concrete cylinder with a height of 500mm and a cross-sectional diameter of 500 mm. The components such as the direction angle measuring ring 3 and the adjusting mechanism 4 are difficult to be directly arranged on the reinforced concrete member. In order to enable the direction angle measuring ring 3 and the adjusting mechanism 4 to be stably matched with the base 1, an embedded part 7 is embedded in the base 1. The rotating disc 41 and the direction angle measuring ring 3 are arranged on the embedded part 7, so that the rotating disc 41 and the direction angle measuring ring 3 can be stably installed, and the service life of the angle reflecting device is prolonged.

In some embodiments, as shown in fig. 2 and 3, the angle reflection device further includes a connecting rod 8 and a nut 9, the connecting rod 8 is inserted into the embedded part 7 and the rotating disc 41, and the nut 9 is used for fixing the connecting rod 8 to lock the rotating disc 41.

It can be understood that, after the azimuth angle of the corner reflector is adjusted to make the incident angle of the radar signal coincide with the normal direction of the corner reflector 2, the rotating disc 41 needs to be fixed on the embedded part 7, so as to prevent the rotating disc 41 from rotating due to external action and affecting the application of the corner reflector 2, and facilitate the adjustment of the pitch angle of the corner reflector 2. Specifically, the rotating disc 41 can be locked on the embedded part 7 through the arrangement of the nut 9 and the connecting rod 8.
