レーダシステム及び車両
Document Type and Number:
Japanese Patent JP7369852
Kind Code:
B2
Abstract:
A radar system (400) and a vehicle are provided, so that when high angular resolution is obtained, a quantity of transmit antennas and a quantity of receive antennas are reduced, to reduce design and processing difficulty. The radar system (400) includes: a transmitter (401), configured to transmit a radar signal; and a receiver (402), configured to receive an echo signal obtained after the radar signal is reflected by a target, where a transmit antenna array of the transmitter (401) and a receive antenna array of the receiver (402) are used to form a virtual linear array and a virtual planar array, the virtual linear array includes a uniform linear array in a first direction, the virtual planar array includes a uniform planar array, and a first spacing between two adjacent array elements in the uniform linear array is less than a second spacing between two adjacent array elements in the first direction in the uniform planar array.
