1. An estimation and identification apparatus, comprising:
a plurality of tracking devices, each of which in operation, emits an electromagnetic wave or a sound wave, and detects a position of an identification target holding a radio communication terminal, based on a reflected wave of the electromagnetic wave or the sound wave by the identification target;
a plurality of radio communication devices, each of which in operation, performs radio communication with the radio communication terminal, and receives identification information of the radio communication terminal from the radio communication terminal; and
analysis circuitry, which, in operation, identifies the identification target and estimates the position of the identification target, based on a result of the radio communication, the detected position of the identification target, and the identification information, wherein:
the plurality of radio communication devices each have a coverage area that includes an area not overlapping with each other, and that is narrower than a detection area of each of the plurality of tracking devices, and
the analysis circuitry identifies the identification target and estimates the position of the identification target when the radio communication terminal enters the coverage area of each of the plurality of radio communication devices.
