1. A method for radar-based monitoring of a rearward area of a truck, the truck including (I) a cabin on which a radar device is installed and (II) a semitrailer connected to the cabin, the method comprising the following steps:
ascertaining presence of an object and an initial determined position of the object using the radar device;
determining an alignment of the semitrailer relative to the radar device;
determining that the object whose presence has been ascertained is likely at least partially concealed by the semitrailer from the radar device;
determining, based on the determined position of the semitrailer relative to the radar device, an expected reflection behavior of radar waves reflected by the semitrailer to the radar device; and
correcting, based on the determined expected reflection behavior of radar waves reflected by the semitrailer, the initial determined position to a true position of the object.
