Abstract
Abstract An antenna system includes a plurality of transmit elements spaced apart by a first dimension and a plurality of receive elements spaced apart by a second dimension, such that the first dimension is a non-integer multiple of the second dimension and the second dimension is a non-integer multiple of the first dimension. A method includes transmitting a signal from a plurality of transmit elements spaced apart by a first dimension and receiving a portion of the transmitted signal reflected from an object via a plurality of receive elements spaced apart by a second dimension, such that the first dimension is a non-integer multiple of the first dimension and second dimension is a non-integer multiple of the first dimension.
