Abstract：Nowadays wind profiler radar has been widely used in local weather forecast,air control,air pollution prevention and so on,has a important significance on the development of national economy.The fault rate of radar equipment increase with the increasing of service life.CFL-03 type wind profiler radar has realized a full solid,modular design,the relevant spare parts has been ordered by many meteorological bureau,so basically we just need to do fault diagnosis,determine the fault location,replace spare parts,and the equipment can resume normal work.According to the composition of the CFL-03 type wind profiler radar,the fault location is analyzed.There are four common fault locations,first is the monitor board on monitor combination,second is the standard frequency components and reference components of the receiver,third is power components of transmitter and switching board of beam control,fourth is one to six power divider.In the fault judgment process,the simplest way is to use the fault indicating lamp on extension combination and fault information indicator on software interface.In addition,using the three tables,oscilloscope,spectrum analyzer and vector network analyzer can further determine the fault.
