Abstract
A method for determining an occupancy state of a parking space of a parking area is described. A device that includes at least one radar sensor and a processing unit, the processing unit being configured to carry out the method, are described. Furthermore, a parking area that includes at least one parking space, the parking space including the device is described.

A method for determining an occupancy state of a parking space, comprising the following method steps:
- a. detecting radar measured values of multiple radar channels in each case at different points in time within a predefined time period using at least one radar sensor, each of the radar measured values being made up of a real part and an imaginary part;
- b. transforming the radar measured values for the different points in time into a polar coordinate system;
- c. determining both a first parameter and a second parameter of each of the transformed radar measured values using a linearized least-squares polynomial fit method;
- and
- d. determining the occupancy state of the parking space as a function of the first parameter.
