Target detection system, detection method, and detection information processing program

A target detection method used for a target detection system which comprises at least two target-detecting transmitters/receivers capable of changing setting of detection azimuth placed at a prescribed interval;

• and a main control device comprising a position calculating module which specifies a position of the target based on azimuth information of the target detected by each of the transmitters/receivers, wherein:
• a signal transmitting/receiving module of each of the transmitters/receivers operates simultaneously or individually to change setting of an azimuth of a target detection area and a transmitting azimuth of a transmission signal sequentially to detect the target, and collects information of the azimuth at which the target exists;
• the position calculating module of the main control device fetches and holds the azimuth information regarding the target collected by each of the signal transmitting/receiving module;
• and
• the position calculating module performs superimposing processing on each piece of the held azimuth information on the basis of the positional information of each of the transmitters/receivers to specify the position of the target.

A non-transitory computer readable recording medium storing a detection information processing program used for a target detection system which comprises at least two target-detecting transmitters/receivers capable of changing setting of detection azimuth placed at a prescribed interval and a main control device comprising a position calculating module which specifies a position of the target based on azimuth information of the target detected by each of the transmitters/receivers, the program causing a computer provided to the main control device to execute:

• a transmitter/receiver operation control function which operates each of the transmitters/receivers simultaneously or individually;
• an azimuth information collecting processing function which collects azimuth information showing an azimuth at which the target exists within a target detection area transmitted from each of the transmitters/receivers and reception information regarding the azimuth received at each of the transmitters/receivers;
• an azimuth information holding function which fetches and holds the collected azimuth information regarding the target and reception information corresponding thereto;
• and
• a target position specifying processing function which specifies the position of the target by performing superimposing processing on each piece of the held azimuth information and the corresponding reception information on the basis of the positional information of each of the transmitters/receivers.
