[0001] The utility model relates to the technical field of radar teaching aids, in particular to a Doppler weather radar teaching aid. Background Art

[0002] Doppler weather radar is an important part of meteorological observation and one of the important bases for weather forecast and meteorological service. The working mode of weather radar is to intermittently emit electromagnetic waves (called pulsed electromagnetic waves) into the air. Due to the large radiation when the radar is working, it is impossible to visit or study it at close range. The previous teaching or popular science methods are often based on picture explanations or static learning when the radar is turned off, lacking an intuitive and overall dynamic demonstration process. Moreover, there are relatively few Doppler weather radar models on the market, and even fewer that can dynamically demonstrate the working status. Utility Model Content
