Abstract: An embodiment of an antenna array includes a transmit antenna and a receive antenna. The transmit antenna has, in one dimension, a first size, and has, in another dimension that is approximately orthogonal to the one dimension, a second size that is greater than the first size. And the receive antenna has, in approximately the one dimension, a third size that is greater than the first size, and has, in approximately the other dimension, a fourth size that is less than the second size. For example, such an antenna array, and a radar system that incorporates the antenna array, can provide a high Rayleigh resolution (i.e., a narrow Half Power Beam Width (HPBW)) with significantly reduced aliasing as compared to prior antenna arrays and radar systems for a given number of antenna-array channels.
