Abstract
The utility model relates to a balloon radar system that comprises an aerial part and a ground part. The aerial part comprises a balloon, a rotating hinge, a sling, and a radar antenna that is fixedly connected with the cabin body of the radar, and electric propellers that are arranged on both sides of the antenna. A motor is used for driving the propellers to rotate in the opposite directions, so that the antenna beams can rotate around a vertical shaft to form the orientation scanning of the beams and to eliminate the ''rotary joint'' that is necessarily required by a conventional radar; the ground-aerial wireless communication link is used for directly transmitting the radar target echo through radio frequency, which does not transform the radar target echo; a satellite positioning receiver is used for acquiring the three-dimensional position of the aerial part; a magnetic orientation sensor is used for acquiring the directive data of the orientation of the antenna beam; the directive data and the data of the three-dimensional position of the ground are used together for transforming the coordinates, so that the target data detected by the radar can be dealt with and displayed on the ground.
Description
Technical field
The utility model relates to a kind of balloon radar system, free in and two ingredients in ground; Utilize balloon that radar is gone up to the air, farther when visual range that radar can the detection of a target is provided with on ground than radar; Utilize the empty radio communication in ground to transmit the radar detection data, simplify the composition of the aerial unit of radar.
Background technology
Owing to be subjected to ground to influence influence with earth curvature, the radar system that is arranged on ground can't detect low latitude, hedgehopping and the earth curvature target under blocking, cause the blind area of radar detection, raise the distance that radar height overhead can increase the detectable target of radar as far as possible.Now, people are installed in radar on the high mountain or on the aircraft, its purpose is exactly in order to increase the distance of the detectable target of radar.Radar is installed on the high mountain, and the construction construction of radar station needs expensive fund; The radar installation can be obtained farther detection range aboard, but the installation of rebecca not only has very high technical requirement, and the cost of use of radar is also very high.When no matter radar is worked on the ground or aboard, for realizing that the target on the different directions is surveyed, the radar antenna wave beam need scan in the orientation.Radar antenna realizes that azimuth scan needs the parts of a kind of being called " rotary joint ", and " rotary joint " can guarantee that the radio-frequency (RF) energy of transmitter is fed on the radar antenna and the target echo signal of reception is fed to receiver when antenna rotates." rotary joint " increased the complicacy of radar, also makes the radio-frequency power of radar emission and reception be subjected to certain loss.
Summary of the invention
In order to improve the working depth of radar, minimizing is installed in radar on the high mountain and installs constructional difficulties aboard and reduces the cost of use of radar, simplifies the radar component units, removes the radio frequency loss that radar uses " rotary joint " to bring from, the utility model provides a kind of balloon radar system, radar is raised in the air, increase sighting distance, can simplify the radar component units again, remove the radio frequency loss that " rotary joint " causes from.
The technical scheme that the utility model is taked is: during radar is free and the two parts of ground, aerial part has balloon, turning joint, hoist cable, the radar antenna that is fixed together with the radar module body, in the antenna both sides for counter-rotating, promote antenna and do and horizontally rotate, form the electric propeller that antenna beam azimuth scans, the aspect sensor that indication radar locus and antenna bearingt rotational angle are arranged has the high frequency transmitter that directly sends radar target reflected signal, radar antenna rotation and spatial position data with the high frequency form.Above ground portion has the HF receiver of the radar target reflected signal, radar antenna rotation and the spatial position data that receive aerial part high frequency transmitter and send, and the converting means that aerial part coordinate conversion is become the above ground portion three-dimensional coordinate data is arranged.
Utilize a balloon that radar is raised to the high-altitude.The distance of radar altitude and target intervisibility can be calculated with following formula:
L＝4.12×(H
1 1/2+H
2 1/2)(Km)
Wherein, the L-radar to the intervisibility of target distance+
H
1-radar altitude (m)
H
2-object height (m)
For example, when the flying height of the antenna height of radar and target was 100m, then radar was 82.4Km to the maximum line-of-sight distance of target; When the height of balloon radar is the flying height of 20000m and target when being 100m, then radar is 623.86Km to the maximum line-of-sight distance of target.
Structurally, radar antenna is connected with the fixed installation of radar body, does not re-use " rotary joint " between radar antenna and the radar body.In order to realize the rotation sweep of radar antenna, respectively be equipped with one by motor-operated screw propeller at the two ends, the left and right sides of antenna, screw propeller is rotation in the opposite direction separately, produce opposite thrust, form torque, thereby make radar antenna produce the rotation that centers on Z-axis, form the azimuth scan of radar antenna wave beam.
Utilize wireless communication line that target echo is directly transmitted earthward with the radio frequency form, the necessary signal flows of normal radar such as the down coversion of radar target signal, intermediate frequency amplification, signal demodulation, radar data processing, display control terminal all carry out on ground.
The utility model beneficial effect is that balloon has promoted radar altitude, has increased the visual detection distance of radar; Counter-rotational screw propeller promotes antenna array and rotates, and produces beam scanning, has saved " rotary joint ", has removed the radio-frequency loss that causes because of " rotary joint "; The empty wireless data transmission in ground has been simplified the composition of the aerial unit of radar.
