Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-5, a preferred embodiment of the composite test system of the present invention is shown.

Referring to fig. 1, the composite test system of the present embodiment includes: a first testing device, a second testing device and a turntable 1. The measured piece is arranged on the rotary table 1. The first testing device is used for measuring the radiation performance of the tested piece; the second testing device is a radar target simulation testing device. The second testing device is arranged in an area which can not be reached by the transmission signal and the reflection signal of the first testing device.

Referring to fig. 2 and 3, in the present embodiment, the first testing device is a compact range testing device, and includes a feed source 5 and a reflecting surface 6; the feed antenna of the feed 5 is disposed at the focus of the parabolic curved surface of the reflecting surface 6. The paraboloid curved surface of the reflecting surface receives spherical waves sent by the feed source, and the spherical waves are converted into plane waves after being reflected and sent to a quiet area in a compact range.

Of course, the first testing device is not limited to the compact field testing device, and may be a direct field testing device, that is, an antenna probe is used for testing. The utility model discloses do not limit to this.

Referring to fig. 4 and 5, in the present embodiment, the second testing device includes a first radar simulator and a second radar simulator, a first radio frequency front end 31 of the first radar simulator is fixedly connected to the holding pole 4, and a second radio frequency front end 32 of the second radar simulator is also fixedly connected to the other holding pole 4. The holding pole 4 where the second radio frequency front end 32 is located can move along the arc-shaped slide rail 2.

When the second testing device is used, the arc-shaped slide rail 2 enables the second radio frequency front end 32 of the second radar simulator to move with a track as an arc by taking the tested piece as a circle center. By means of the arc-shaped slide rail 2, the specific angle of the second radio frequency front end 32 can be always ensured to be aligned with the tested piece. Therefore, when the input power of the second rf front end 32 is stable, the gain is also stable; the space loss of the electromagnetic wave at a fixed distance is fixed under the same environment, and finally the power received by the tested piece is also stable.

In addition, the second rf front-end 31 and the second rf front-end 32 are in signal connection with a radar simulator located outside the darkroom 7. The radar simulator is connected with a PC as an upper computer. The control of each radar simulator, the rotary table and the like is realized by means of a good graphical user interface of the PC.

Referring to fig. 1 again, in the present embodiment, the first testing device, the turntable and the second testing device are distributed in an L shape. The turntable 1 is arranged at the corners of the L-shaped distribution. The first testing device and the second testing device are respectively positioned at the free ends of the L-shaped distribution. As can be seen from fig. 1, the first rf front end 31 of the first radar simulator, the second rf front end 32 of the second radar simulator, the holding pole 4, and the slide rail 2 are all located at one free end of the L-shaped distribution, and the reflective surface 6 and the feed source 5 of the second testing device are located at the other free end of the L-shaped distribution

In order to arrange the second testing device in the area where neither the transmission signal nor the reflection signal of the first testing device can reach, a wave-absorbing structure is preferably arranged between the first testing device and the second testing device.

It should be noted that the second testing apparatus in the present embodiment includes two radar simulators, but the present invention is not limited thereto. It is also possible to include only one radar simulator, or a plurality of radar simulators. If a plurality of radar simulators are included, the position of the radio-frequency front end of at least one radar simulator is fixed, and the radio-frequency front ends of the rest radar simulators can move along the arc-shaped sliding rail; and the radio frequency front ends of all the radar simulators can move along the arc-shaped slide rail. In one embodiment, the radio frequency front end of the radar simulator is a horn antenna, and the sliding type of the rest of the holding poles fixedly connected with the horn antenna is realized by sliding the holding poles on the arc-shaped sliding rail.

The utility model discloses a first testing arrangement, second testing arrangement and revolving stage in the embodiment set up in the darkroom, and the darkroom also can be designed into L type darkroom, and the wall of darkroom is provided with absorbing structure.
