Abstract: The invention relates to a method and a measuring arrangement for detecting an object (3) hidden behind an article (1). The method comprises the following steps: applying a first alternating voltage (5) to a first sensor (7); applying a second alternating voltage (9) to a second sensor (11) arranged adjacent to the first sensor (7); determining an effect (15) of the article (1) on at least one of the alternating voltages (5, 9) depending on a distance (13) of the sensor (7, 11) to the article (1); determining a change (17) in the dependent effect (15) occurring during a movement (19) of the sensor (7, 11) along the article (1); and detecting the object (3) in accordance with the change (17) of the dependent effect (15). In this way, a detection of an object hidden behind an article is improved such that the object can be recognized as independently as possible from a relative position of the device to the article, in particular, an angular position, in particular also if the device for detecting the object is manually moved beyond the article.
