Radar apparatus, data processing method, and data processing program

A data processing method comprising:

• transmitting, by a transmitting module, electromagnetic waves;
• receiving, by a receiving module, reflected electromagnetic waves reflected by a target object;
• generating, by a generation module,
• amplitude data of the reflected electromagnetic waves and
• displacement data indicating velocity or acceleration of the target object based on the reflected electromagnetic waves for each cell on a coordinate having an azimuthal direction and a distance direction;
• and
• determining, by a determination module, whether a cell of interest corresponds to a boundary cell to be a boundary to divide the target object based on a comparison result between the displacement data of the cell of interest among a plurality of cells of interest and the displacement data of the cell of interest being close to the cell of interest in the azimuthal direction or the distance direction.

A non-transient computer-readable recording medium, recording a data processing program, enabling a computer to:

• transmit, by a transmitting module, electromagnetic waves;
• receive, by a receiving module, reflected electromagnetic waves reflected by a target object;
• generate, by a generation module,
• amplitude data of the reflected electromagnetic waves and
• displacement data indicating the velocity or acceleration of the target object based on the reflected electromagnetic waves for each cell on a coordinate having an azimuthal direction and a distance direction;
• and
• determine, by a determination module, whether a cell of interest corresponds to a boundary cell to be a boundary to divide the target object based on a comparison result between the displacement data of the cell of interest among a plurality of cells of interest and the displacement data of the cell of interest being close to the cell of interest in the azimuthal direction or the distance direction.
