Problems solved by technology
In 2004, the Frenchman MP.Boussaion et al. published an article explaining the principle of the camera radiosonde [17], but the radiosonde developed by them was only calibrated in the laboratory, and did not carry out the cloud-penetrating observation in the field.
There are no videosonde products and related development reports in China, and foreign videosonde products are subject to a technical blockade against China, and related products are not sold to China

Embodiment Construction
[0009] Below in conjunction with accompanying drawing, the patent of the present invention is described in detail as follows:
[0010] Such as figure 1 As shown, the present invention discloses a radiosonde-based automatic tracking system and method, including a ground system and an air system. The ground system mainly includes 1 measurement and control computer, 2 drive circuits, 3 servo systems, 4 directional receiving antennas, 5 electronic Compass and inclinometer. Air system 6GPS module, power supply system and the carrier used to send the GPS module to the air. The measurement and control computer sends a pulse signal to the drive circuit through the host software to control the servo system. The directional receiving antenna is installed on the servo system and rotates with the rotation of the servo system. 5 The electronic compass and inclinometer are installed on the servo system to measure the azimuth and depression angle in real time. It is provided to the upper ...

The present invention discloses a sonde-based automatic tracking system and method. The method comprises that coordinate transformation is carried out according to current GPS positioning data of a sonde and GPS positioning data of a place where a cloud deck is disposed, a pitch angle and an azimuth angle of the sonde in a local coordinate system are calculated and are compared with a current posture of a directional antenna, and the posture of the antenna is adjusted according to angle difference values. The GPS tracking technology is applied to a sonde system for the first time, and with adoption of the direction antenna and the tracking system, wireless transmission distance is greatly prolonged and can reach 20 km. Through lab debugging and multiple outdoor tests, feasibility of the design scheme is proven, and test results shows that the system operates stably, communication distance is long, and the anti-interference capability and the practicability are good.
Description
technical field [0001] The invention relates to the field of atmospheric data collection, in particular to an automatic tracking system and method based on a radiosonde. Background technique [0002] With the advancement of science and technology, human activities are increasingly dependent on meteorological information. Regardless of the military, aerospace and other scientific research work, or agriculture and people's daily travel are greatly affected by the weather, therefore, research on various meteorological activities has received more and more attention. At present, the atmospheric data acquisition method mainly uses the carrier to send the radiosonde device into the cloud layer, and uses the sensor device on the radiosonde device or remote sensing technology to obtain relevant data in the cloud layer during the movement of the radiosonde in the cloud layer. According to the difference of the radiosonde carrier, it can be divided into: rocket method, aircraft metho...
