ABSTRACT:
A target identifying apparatus identifies a target from a first signal distribution and includes a calculation section, a target signal identifying section, a subtraction section, and a correction section. The calculation section calculates a quadratic approximate expression in the first signal distribution. The target signal, identifying section identifies a signal contained in the quadratic approximate expression as a single target signal. The subtraction section subtracts a value of the quadratic approximate expression from a value of the first signal distribution to generate a second signal distribution. When the one of the beam angle and the frequency corresponding to a maximum value of the second signal distribution is in a range where the value of the quadratic approximate expression is subtracted or is in a vicinity of the range, the correction section corrects the second signal distribution based on the quadratic approximate expression.
