the working frequency of radar the shorter the wavelength, the higher the electromagnetic wave, the easier it is tilted in the solid surface has a better reflection of, and have a narrow beam width, which can effectively avoid obstacles, still can make high frequency radar using smaller antenna. Radar level meter used in many conditions, comprehensive performance is superior to other measuring instrument perfect radar products. Radar thermometer get extensive application in petroleum and chemical industry. In the process of production, due to the lack of enough understanding of this new type of instrument and fault processing methods, is not the fault of the thermometer, effectively solve the radar in time in order to solve the problem of radar fault common thermometer, through theoretical analysis and field test method, this paper expounds the causes of thermometer faults, analyzed the causes of failure, low energy is emitted by a radar thermometer is extremely short microwave pulse by transmitting and receiving antenna system.

radar sensor using special time interval adjustment technology per second echo signal amplification, positioning, and then carries on the analysis processing. So the radar sensor can be 0. 1 s in precise detail analysis of these be amplified echo signal, do not need to spend a lot of time to analyze the frequency. The biggest characteristic is noticeable efficacy in harsh conditions. Toxic medium, and corrosive medium, whether solid, liquid or powder, slurry medium, it can be measured.
