Abstract
Disclosed is a method and apparatus for estimating a signal source, the method including receiving, in at least one receiving node, a signal emitted from a signal source, extracting a steering matrix corresponding to a virtual antenna array by vectorizing the signal received in the at least one receiving node, and estimating a location of the signal source based on the steering matrix.
Claims20
A method of estimating a location of a signal source, the method comprising:
- receiving, in at least one receiving node, a signal emitted from a signal source;
- extracting a steering matrix corresponding to a virtual antenna array by vectorizing the signal received in the at least one receiving node;
- and
- estimating a location of the signal source based on the steering matrix,
- wherein the extracting the steering matrix comprises extracting the steering matrix based on a location of the signal source to be estimated,
- wherein the extracting the steering matrix comprises:
- generating a first direction vector based on a first location of a first receiving node among the receiving node,
- generating a second direction vector based on a second location of a second receiving node among the receiving node, and
- extracting the steering matrix based on the first direction vector and the second direction vector.
