Abstract

Apparatus and method for detecting calling location of radio signal using short pulses from a calling station. The apparatus for detecting calling location of radio signal, comprising: a plurality of antenna systems (101, 102 and 103), each antenna system having a plurality of antennae, for detecting strength of the radio signal and code of calling station (109) if the radio signal of which the strength is larger than a threshold is received; calling location detecting means (107) for detecting the calling location of radio signal based on relation between distances between the antenna systems and receiving angles, after obtaining the receiving angles of the radio signal received at each the antenna system using difference of the radio signal received at a plurality of the antennae and detected; and output means (108) for receiving the calling location of radio signal and the code of the calling station, and for outputting information of the calling station by retrieving subscriber database based on the code of the calling station and the calling location.
