1. A radar apparatus comprising:
at least one memory configured to store one or more instructions; and
at least one processor configured to execute the one or more instructions to:
acquire a radar signal acquired by measurement using a transmission antenna and a reception antenna, and a measurement time of the radar signal;
hold a setting of a velocity candidate set of a target object;
generate a radar image applied with movement compensation by using each velocity candidate;
perform ranking on each velocity candidate for each of one or more cells by using the radar image applied with movement compensation;
compute a value acquired by totaling a score based on the rank for all cells for each velocity candidate;
select an estimated velocity from the velocity candidate set, based on comparison of each generated radar image and based on the totaled value; and
generate a final output image applied with movement compensation using the estimated velocity.
