Abstract
The embodiments of the present disclosure relate to a radar control device and method. Specifically, a radar control device according to the present disclosure may include a receiver for receiving vehicle driving information for a host vehicle from a radar, an APS determiner for determining an angular power spectrum (APS) for a predetermined frequency based on the vehicle driving information if an object is detected in the vehicle driving information, and an object determiner for determining a position of a measurement value based on the determined APS, and determine whether there are a plurality of objects based on the position of the measurement value.
Claims16
A radar control device comprising:
- a receiver for receiving vehicle driving information for a host vehicle from a radar;
- an APS determiner configured to determine an angular power spectrum (APS) at a predetermined frequency based on the vehicle driving information if an object is detected in the vehicle driving information;
- and
- an object determiner configured to determine a position of a measurement value based on the determined APS, and determine whether there are a plurality of objects based on the position of the measurement value,
- wherein the APS determiner is configured to sum a plurality of APSs determined at different times for a predetermined time period to determine a sum of angular power spectrum (SAPS), and the object determiner is configured to determine whether there are the plurality of the objects based on the position of the measurement value determined in the SAPS.
