2d phased subarray mimo radar

A two-dimensional phased subarray MIMO radar apparatus comprising:

• a transmission array configured to emit transmission signals, which are orthogonal to each other, towards a target object, extending in a first direction, and comprising a plurality of transmission phased subarrays;
• and
• a reception array configured to receive reflected signals, which are reflected from the target object, among the emitted transmission signals, extending in a second direction intersecting the first direction, and comprising a plurality of reception phased subarrays,
• wherein each of the plurality of transmission phased subarrays comprises a plurality of transmission antennas, and each of the plurality of reception phased subarrays comprises a plurality of reception antennas,
• wherein a first transmission phased subarray and a second transmission phased subarray are adjacent transmission phased subarrays among the plurality of transmission phased subarrays, and a spacing from an end of the first transmission phased subarray in the first direction to an end of the second transmission phased subarray in the first direction is a first spacing, the first spacing being greater than or equal to an aperture of each of the plurality of transmission phased subarrays, and
• wherein a first reception phased subarray and a second reception phased subarray are adjacent reception phased subarrays among the plurality of reception phased subarray, and a spacing from an end of the first reception phased subarray in the second direction to an end of the second reception phased subarray in the second direction is a second spacing, the second spacing being greater than or equal to an aperture of each of the plurality of reception phased subarrays.
