Embodiment Construction

[0057] The present invention will be further described below in conjunction with accompanying drawing.

[0058] Such as figure 1 , 2 As shown, the artificial rain enhancement anti-hail bomb explosion point sound location system provided by the present invention includes a control center and N regional measurement and control units interacting with the control center.

[0059] The control center is responsible for the control management, resource scheduling, information exchange and data storage of the entire system; the control center can also be equipped with a meteorological measuring station, which is responsible for providing information on environmental conditions such as wind speed, wind direction, temperature and air pressure in the area covered by the system. Used as a reference value for subsequent big data analysis.

[0060] The N regional measurement and control units are arranged according to the terrain distribution of the work site, and the set of N regional me...

Abstract

In order to solve the problem of large positioning deviation of an existing positioning method for an explosion point of an artificial precipitation enhancement hail suppression bomb, the invention provides an artificial precipitation enhancement hail suppression bomb sound positioning system and a positioning method. According to the method, a positioning mode based on the fusion of the arrival distance difference and the arrival angle of the hail suppression bomb explosion point sound wave signals is adopted, the influence of clock stability and environmental factors is small, and thereforethe positioning deviation is small. In addition, a plurality of single microphone nodes are arranged, so that there are many redundant parameters and parameters for position calculation, and the position estimation of the explosion point of the precipitation enhancement hail suppression bomb is more accurate.

Description

technical field [0001] The invention relates to an acoustic positioning system for artificial rain-increasing and anti-hail bomb explosion points. Background technique [0002] Weather modification operations are of great significance to my country's agriculture and ecological governance. The anti-aircraft gun system is the most widely used launching device today. The accuracy of rain-enhancing and hail-proof projectiles is one of the important indicators for evaluating the effectiveness of weather modification operations. Therefore, real-time Accurately measuring the coordinates of the explosion point of anti-hail bombs is one of the important measurement tasks for the effectiveness of weather modification operations. [0003] At present, the location of the explosion point of the artificial rain-enhanced hail bomb is mainly measured by the detection device to measure the pitch angle and azimuth angle of the launch system, and then use the geometric model to calculate the co...
