Abstract
A single antenna single reader (SASR) system and method for locating a tag. The reader connects to a single antenna that is in motion. The reader transmits an interrogation signal to the tag. The reader receives a response signal from the tag. The reader determines the range of the tag from the reader, the received signal strength (RSS) of the response signal at the reader from the tag, and the maximum correlation of the response signal at the reader from the tag. The reader determines the location of the tag using range of the tag from the reader, received signal strength and maximum correlation of the response signal.
