Abstract
An apparatus including a radar sensor configured to track a target in motion, and a processor configured to determine a first bit frequency and a second bit frequency and determine based on the first bit frequency and the second bit frequency whether or not the target is a ghost target, in a case where a range gap between an n-th frame and an (n−1)-th frame is above a first value.
Claims14
An apparatus for detecting a target, the apparatus comprising:
- a radar sensor configured to track the target in motion on a basis of a frame that varies with a time slot;
- and
- a processor configured to:
- determine a first beat frequency between an (n−1)-th frame corresponding to a first preceding location of the target and an (n−2)-th frame corresponding to a second preceding location of the target,
- determine a second beat frequency between an n-th frame corresponding to a current location of the target and the (n−1)-th frame, and
- determine based on the first beat frequency and the second beat frequency whether the target is a ghost target in response to a range gap between the n-th frame and the (n−1)-th frame being above a preset first value.

A method of tracking a target, the method comprising:
- tracking, by a radar sensor, the target in motion on a basis of a frame that varies with a time slot;
- and
- determining, by a processor, based on a range gap between an n-th frame and an (n−1)-th frame being above a preset first value, whether the target is a ghost target, based on a first beat frequency between the (n−1)-th frame corresponding to a first preceding location of the target and an (n−2)-th frame corresponding to a second preceding location of the target and a second beat frequency between the n-th frame corresponding to a current location of the target and the (n−1)-th frame.
