Abstract In order to improve the accuracy of short-time rainstorm early warning,this paper studies the design of short-time rainstorm early warning information release system based on multi-sensor information fusion.Using PCR millimeter wave radar sensor as the hardware device of the system to collect cloud height and velocity information.In the stage of short-term rainstorm information prediction,the time series data of rainfall intensity,rainfall range,cloud height and velocity variables are converted into an array by using the unique heat coding method,and a model is constructed to calculate rainfall information,and the model is corrected by using the mean square error;In the stage of short-term rainstorm information release,take the actual geographical range division as the benchmark,match the corresponding information,and issue rainfall information differently.In the test results,the difference between the warning results for 5-minute rainfall in different regions and the actual situation remained stable within 0.03 mm.
