RADAR DEVICE AND AUTOMOBILE PROVIDED WITH SAME

WIPO Patent Application WO/2019/049680

A1

Provided is a radar device and an automobile provided with the same, with which it is possible for an angle of elevation or depression of a target object to be measured accurately and inexpensively using a simple circuit, without using a detecting circuit or an AD conversion circuit having high time resolution. A transmission signal wave Stx modulated by means of multilevel FSK is transmitted from a transmission antenna Tx, and a reflected wave that is reflected back by a target object 7 is received by reception antennas Rx(1), ..., Rx(n-1), Rx(n) as a received signal wave Srx. By employing multilevel FSK as the modulation scheme, a beat frequency between the received signal wave Srx from the target object 7 and the transmission signal wave Stx is the Doppler frequency of the target object 7. Therefore, the angle of elevation or depression φ of the target object 7 is calculated by a calculator 6 from the frequency fi of the transmission signal wave Stx, and not from the frequency of the received signal wave as in the past.
