RADAR DEVICE AND OPERATION METHOD FOR RADAR DEVICE

摘要

PROBLEM TO BE SOLVED: To accurately detect a position of an object.SOLUTION: The radar device has: transmission means (a transmission antenna 22) for repeatedly transmitting a pulse signal; reception means (reception antennas 23 and 24) for receiving reflection signals reflected by an object; sampling means (A/D conversion unit 28) for sampling a reflection signal in each field in prescribed cycle more than once and performing equivalent time sampling by shifting timing to start sampling by the field when a period after the pulse signal is transmitted until the next pulse signal is transmitted is the field; detection means for detecting an object on the basis of the obtained data; and correction means (an operation processing unit 14) for correcting a position of the object on the basis of an elapsed time after sampling of the field where the object is detected is performed until sampling of all the fields is over, the object, and relative speed of itself.
