Design of Severe Convective Weather Early Warning System Based on Phased Array Doppler Radar Technology
To avoid the impact of sudden disasters on personal and property safety,a strong convective weather warning system based on phased array Doppler radar technology is designed to address the issues of multiple interference factors in the weather warning process and low pixel accuracy of radar imaging.Data acquisition chip and circuit mixer are designed to obtain the sta-ble operation of dual channel interface through different voltages.Based on phased array radar Doppler technology,strong con-vective weather data and preliminary processing,we format Doppler radar data,compute reflectivity level structure and vertical gradient reflectivity,avoid interference factors,calculate maximum fuzzy speed and maximum fuzzy distance,get fuzzy parame-ters,radar speed back,thus,a strong convective weather early warning model is set up,which provide a new severe convection weather warning system.Experimental results show that the pixel accuracy of different radial distances and different azimuth angles ob-tained by the system is less than 0.03,which can improve the radar imaging accuracy and get more accurate warning results.
