| Abstract: | The technology of radar material level measurement is the faster developing area in material level measurement,but the development of such radar instruments of this area is comparatively slow in our country.Thus,in accordance with two of the measuring modes occupied most of the market of radar level meters,i.e.radar pulse measurement and continuous wave linear frequency modulation measurement,their signal processing patterns are analyzed in detail,and their merits and demerits are compared respectively.The ... |
