Abstract
A radar system and method is provided, in which the radar system includes a first transmitting portion of antenna elements, a second transmitting portion of antenna elements, and a receiving portion of antenna elements, such that the receiving antenna elements form a plurality of subarrays that represent real and synthetic antenna elements. The radar system further includes a transceiving device having a switching matrix. At least first and second switching transmit antenna elements are configured and time-multiplexed, wherein a receive aperture of the receiving antenna elements is increased. A first signal transmitted is received by the real antenna elements and a second signal transmitted is received by the real antenna elements, and combined so that the signals received from the first switching transmit antenna element represents a signal received by the real receive antenna element, and the signal received from the second switching transmit antenna element represents a signal received by the synthetic receive antenna element.
