| titleOfInvention | METHOD AND DEVICE FOR MEASURING THE DISTANCE TO AN OBJECT. |
| abstract | Method and device for measuring the distance of an object in particular the distance from the surface (17) of a liquid (16) in a container (15). An antenna (11) is arranged at a certain distance from the surface (17) towards which it is directed, this antenna being connected to a measuring unit (12), a channel unit (13) and a control unit (14). ). A microwave signal of a predetermined frequency is emitted into the measuring unit (12), part of which serves as a reference signal, while another part is entered into the antenna (11) and transmitted in surface direction (17). From the reflected signal received by the antenna and directed to the measurement unit (12) and from the reference signal, a function of the input reflection coefficient of the antenna is formed. This function is adapted to the current condition. We perform a Fourier transformation of a series of values of this function for a certain series of measurement frequencies, from which we calculate the distance from the surface. |
