summing a plurality of APSs determined at different times for a predetermined time period to determine a sum of angular power spectrum (SAPS),

wherein the determining of whether there are the plurality of objects comprises determining whether there are the plurality of the objects based on the position of the measurement value determined in the SAPS.

10. The radar control method of claim 9 , wherein determining whether there are a plurality of objects comprises determining a position corresponding to a peak value in the APS as the position of the measurement value.

11. The radar control method of claim 9 , wherein determining whether there are a plurality of objects comprises determining that there are a plurality of objects if a number of peak values determined in the SAPS is plural.

12. A radar control method comprising:

receiving vehicle driving information for a host vehicle from a radar;

determining 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

determining a position of a measurement value based on the determined APS, and determining whether there are a plurality of objects based on the position of the measurement value,

wherein determining the APS comprises determining a sum of angular power spectrum (SAPS) based on the APS, and determining whether there are a plurality of objects comprises determining whether there are a plurality of the objects based on the position of the measurement value determined in the SAPS,
