| 摘 要： | 1 Introduction It is absolutely necessary to use high precision level measure systems on many occasions. Radar level meter has a great market and application foreground as a new type of high precision and non- maintaining level mea- sure device without touch. It adopts microwave measure technology, has no movable parts or blind measure area and can detect single target. Though it has a near affect range and a low emission power, it has an advantage of high measure precision, simple reliable ci…

| Abstract: | A new method of increasing the range measure preci- sion by Chirp- Z transform in the level Radar has been put up in this paper. The main assignment of this research is to accom- plish the FFT and Chirp- Z transform. At the same time, the af- fection of the two range measure methods has been analyzed in this paper. This method can increase both the calculation effi- ciency and range measure precision remarkably by theory calcu- lating and digital emulation. |
