| Abstract: | Metallurgical radar was developed which can be used in high temperature and hash production environments.It adopted an improved frequency-modulated continuous wave principle and enhanced the real-time performance of solid material level measurement.An intelligent time-varying threshold signal processing method was proposed to solve the radar ranging accuracy problem caused by the change of solid material surface reflection coefficient in a blast furnace.Measurement results in a solid-powder state material s... |
