Microwave rain attenuation law based artificial rainfall experimental method with adjustable link length

A microwave rain attenuation law based artificial rainfall experimental method with an adjustable link length, comprising the following steps of:

• (1) designing and calculating rainfall intensities in different return periods to form an experimental rainfall process, and simulating artificial rainfall by using an artificial rainfall hall;
• (2) building a corner reflector and adjusting an arrangement point and an emission angle of the corner reflector to dynamically adjust the microwave link length;
• (3) installing an experimental microwave device, and selecting a microwave link with a specific microwave frequency band as an experimental link;
• (4) using a self-recording rain gauge to obtain measured data on the experimental link under different rainfall intensities;
• and
• (5) according to the measured data, obtaining a whole process of the experimental rainfall intensity change, and analyzing and calculating the microwave rain attenuation law.
