Target tracking apparatus, target tracking method, and target tracking program

A target tracking method for tracking a target in a detection area, comprising:

• receiving a reflected signal wave reflected in the detecting area by electromagnetic waves transmitted through an antenna;
• outputting echo data indicating the correspondence between the position in the detecting area and the level of reflected waves;
• detecting one or a plurality of potential tracking targets having a level of the reflected wave equal to or higher than a predetermined value based on the echo data;
• estimating the predicted position of the potential tracking targets in the future;
• setting an area where the potential tracking targets to be tracked may exist, including the predicted position;
• selecting a tracking target from one or a plurality of the potential tracking targets in the area;
• tracking the selected tracking target as a tracking target.

A non-transitory computer-readable medium having stored thereon computer-executable instructions which, when executed by a computer, cause the computer to:

• receive a reflected signal wave reflected in the detecting area by electromagnetic waves transmitted through an antenna;
• output echo data indicating the correspondence between the position in the detecting area and the level of reflected waves;
• detect one or a plurality of potential tracking targets having a level of the reflected wave equal to or higher than a predetermined value based on the echo data;
• estimate the predicted position of the potential tracking targets in the future;
• set an area where the potential tracking targets to be tracked may exist, including the predicted position;
• select a tracking target from one or a plurality of the potential tracking targets in the area;
• track the selected tracking target as a tracking target.
