1.1 Principle Of Measurement
The ultrashort microwave pulse with very low emitted energy is sent and received by
antenna system. Radar wave travels at the speed of light. Runtime can be transformed into thing level signal by electronic components. A kind of special time extension method is able to guarantee
stable and precise measurement in a very short time.
Even if the condition is more complex, and there is false echo, we also analyze accurately the echo of thing level by using latest microprocessor
technology and debugging software.
1.2 Input
Antenna receives reflected microwave impulse, and then transmits the microwave
to the elctronic circuit. Microprocessor deals with the signal and identifies the echo signal that micro-impulse produces on the surface of material. Correct echo signal is identified by
intelligent software, of which precise is up to millimetre size. Distance D to the surface of material is proportional to the time distance of impulse T:
D=C×T/2
Where C is the speed of light
Because the distance of empty tin E is known, material L is:
L=E-D
