Abstract
A radar apparatus and a radar signal processing method are provided. The radar apparatus includes a plurality of transmitting antennas, a plurality of non-uniformly and linearly deployed receiving antennas, a sensor signal processor configured to calculate target range-Doppler data from signals input from a receiving antenna arrangement according to virtual antennas while sequentially driving the plurality of transmitting antennas, and a target position calculator configured to calculate position data of a target from arrangement mapped data obtained by rearranging the virtual antenna-specific range-Doppler data output from the sensor signal processor with reference to antenna configuration related information.
Claims7
A radar apparatus comprising:
- an antenna arrangement including a plurality of transmitting antennas and a plurality of receiving antennas, at least one kind of which are non-uniformly and linearly deployed;
- a sensor signal processor including a range and Doppler processor configured to calculate range-Doppler data for each of virtual antennas from signals input through the plurality of receiving antennas while sequentially driving the plurality of transmitting antennas;
- and
- a target position calculator configured to calculate position data of a target from an arrangement mapped data obtained by rearranging the range-Doppler data calculated by the sensor signal processor according to a two-dimensional spatial arrangement of the virtual antennas.
