Description
Technical field
The present invention relates to technology of instrument and meter field, and in particular to a kind of rocketsonde.
Background technology
Measure free atmosphere temperature that sonde is made of sensor, switching controller and radio transmitter, pressure, wet etc.
The instrument of meteorological element.Divided according to detection height, be mainly divided to low-altitude detection and aerological sounding two classes.
Low-altitude detection is mainly used for the atmosphere elements in 0~20km of acquisition spaces, aerological sounding be mainly used for obtaining 20km~
The atmosphere elements in 65km spaces.Low-altitude detection is mainly transported sonde to the high-altitude of 20km or so using helium balloon, is being risen
Sounding data is transported to Ground Meteorological radar by section by radio transmission, or is jettisoninged using aircraft, with aircraft by with parachute
Sonde is transported to the high-altitude dispensing of 20km or so, and sounding data is transported to weather radar by radio transmission in descending branch.
Sonde is transported to high-altitude and the release of 70km or so using Small Solid power carrier rocket by aerological sounding, is led to
Cross parachute and delay drop, weather radar is transferred in the data that descending branch detects various kinds of sensors.Wind speed, wind direction parameter pass through
Weather radar locating and tracking sonde measures；The data such as temperature, air pressure, atmospheric density are measured simultaneously by the sensor of sonde
Calculate.At present, the radarsonde to be used having based on weather radar physiometry is led and based on satellite navigation Instrumentation system
GPS sondes.
Weather radar system tracks rocketsonde using conical scanning mode and realizes angular surveying, due to mechanism itself
Limitation, will realize stable dynamic tracking measurement, the very little that coning angle can not possibly design, and scan frequency is impossible by technology restriction
Design excessive, causing angular surveying, there are error.Weather radar system is using radar and rocketsonde superregenerative transmitter
Answer method realizes that oblique distance measures, and since superregenerative transmitter is operated in threshold oscillation state in itself, is easily subject to external environment condition
Influence, when performing aerological sounding task, easily produce more " recesses " (recess is that transponder receives radar transmitter
After inquiry, what the hunting power of its own was occurred in moment falls, i.e. answer signal) so that radar range finding is not allowed or can not
Ranging, needs to carry out repeatedly " challenge-response " during ranging in addition, which needs regular hour window, two signals it is same
Step property is bad also to introduce measurement error, cause ranging data there are larger deviation, so as to influence wind speed, wind direction and big airtight
The calculation accuracy of the parameters such as degree.
Satellite navigation Instrumentation system realizes the measurement of sonde position and speed using satellite navigation.Its maximum advantage is
Position, the measurement result accuracy of speed are high, disclosure satisfy that the accuracy requirement of atmosphere elements data calculation.But should from current
From the point of view of situation, due to cannot be guaranteed descending branch whole process gps antenna towards day, there are of short duration in descending branch for the signal of aeronautical satellite
The situation of losing lock, and using the isotropic receiving antenna of pattern-band, Partial angle gain is low, causes data acquisition imperfect, receives star feelings
Condition is had a great influence by external factor such as weather.
The content of the invention
In view of this, the present invention provides a kind of compound rocketsonde of bimodulus, using two kinds of radar and satellite navigation
Location technology, the location data of acquisition are complementary to one another, are mutually authenticated, and improve the computational accuracy of detection data, add detection
The confidence level of data.
Specific embodiments of the present invention are as follows：
A kind of compound rocketsonde of bimodulus, the rocketsonde include meteorological sensor, aeronautical satellite receiving module,
Switching controller and superregenerative transmitter, ancillary equipment are Ground Meteorological radar；
The meteorologic signal collected is transferred to switching controller conversion by the meteorological sensor；

The switching controller is transferred to superregenerative transmitter by after the meteorologic signal received and Measurement and Data Processing；
The superregenerative transmitter realizes the survey to sonde position with Ground Meteorological radar by challenge-response mechanism
Amount, and obtain the meteorologic parameter of sonde relevant position.
Further, the meteorological sensor transmits the meteorologic signal collected after corresponding signal conditioning circuit conversion
To switching controller, the measurement data for setting the sampling period is converted to by switching controller.
Beneficial effect：
The data that the present invention is gathered by satellite navigation, overcome weather radar Instrumentation system measurement angle and oblique distance are accurate
The problem of degree deficiency, can be obviously improved the accuracy of detection data；And the rocketsonde performance of aeronautical satellite Instrumentation system is not
Stablize, position easy losing lock, receive the shortcomings that star situation is had a great influence by weather and made up further through the track and localization of weather radar,
The reliability of whole detection system can be greatly improved；Using two kinds of location technologies of radar and navigation, the location data phase of acquisition
Mutually supplement, be mutually authenticated, improve the computational accuracy of detection data, add the confidence level of detection data.
Brief description of the drawings
