Abstract
A method for processing data associated with at least one radio signal source, said method comprising: receiving at least one multi-path received signal associated with the radio signal source comprising signal components associated with different signal paths, determining at least one property of at least one of the signal components, providing position information characterizing at least one position of an apparatus receiving the at least one multi-path received signal, determining a position of the at least one radio signal source based on the at least one property of at least one of the signal components and on the position information.

A computer-implemented method for processing data associated with a radio signal source (10), wherein an apparatus (100) receives a signal from the radio signal source (10), said method comprising:
- receiving (200) a multi-path received signal (ES-MW) transmitted by the radio signal source (10) comprising signal components (SK-1, SK-2, . . . ) which are associated with different signal paths (SW-1, SW-2, . . . ),
- determining (202) a property (EIG-1, EIG-2, . . . ) of at least one of the signal components (SK-1, SK-2, . . . ),
- providing (204) position information (I-POS), which characterizes a position (POS-100) of the apparatus (100) receiving the multi-path received signal (ES-MW), and
- determining (206) a position (POS-10) of the radio signal source (10) based on the property (EIG-1, EIG-2, . . . ) of at least one of the signal components (SK-1, SK-2, . . . ) and the position information (I-POS).
A non-transitory computer-readable storage medium (SM) comprising instructions (PRG) for processing data associated with a radio signal source (10), wherein an apparatus (100) receives a signal from the radio signal source (10), and the instructions (PRG), when executed by a computer (402), cause the computer to
- receive (200) a multi-path received signal (ES-MW) transmitted by radio signal source (10), comprising the signal components (SK-1, SK-2, . . . ) which are associated with different signal paths (SW-1, SW-2, . . . ),
- determine (202) a property (EIG-1, EIG-2, . . . ) of at least one of the signal components (SK-1, SK-2, . . . ),
- provide (204) position information (I-POS), which characterizes the at least one-position (POS-100) of the apparatus (100) receiving the multi-path received signal (ES-MW), and
- determine (206) a position (POS-10) of the radio signal source (10) based on the property (EIG-1, EIG-2, . . . ) of at least one of the signal components (SK-1, SK-2, . . . ) and the position information (I-POS).
A computer-implemented method for processing data associated with a radio signal source (10), the method comprising:
- receiving (200) a multi-path received signal (ES-MW) transmitted by the radio signal source (10), comprising a plurality of signal components (SK-1, SK-2, . . . ) which are associated with different signal paths (SW-1, SW-2, . . . );
- determining (202), for at least one of the signal components (SK-1, SK-2, . . . ), a property (EIG-1, EIG-2, . . . ) comprising an angle of incidence (EW-1) and an arrival time (AZ-1);
- providing (204) position information (I-POS), which characterizes a position (POS-100) of an apparatus (100) receiving the multi-path received signal (ES-MW), wherein the position information (I-POS) characterizes a surrounding structure;
- selecting (210) a subset of the signal components (SK-1, SK-2, . . . ) as selected signal components (SK-SEL) based on arrival times (AZ-1, AZ-2, . . . ) such that signal components (SK-1, SK-2, . . . ) associated with higher-order reflections are excluded from the selected signal components (SK-SEL);
- identifying (220) an object (OBJ) of the surrounding structure based on the position information (I-POS) and the angle of incidence (EW-1) of at least one selected signal component (SK-SEL), and determining (222) a position (POS-RP) of a reflection point of the at least one selected signal component (SK-SEL);
- determining (206) a position (POS-10) of the radio signal source (10) based on a property (EIG-1, EIG-2, . . . ) of at least one of the selected signal components (SK-SEL) and the position information (I-POS);
- reducing (232) an uncertainty associated with determining the position (POS-10) of the radio signal source (10) by using further signal components, wherein the further signal components comprise signal components associated with higher-order reflections and signal components of at least one further multi-path received signal (ES-MW).
