Patent number: 11796666Abstract: A radar system includes antenna elements and receive channels. An adaptive switch couples the receive channels to a subset of the antenna elements as selected antenna elements. The selected antenna elements receive reflected signals from reflection by objects and each of the receive channels outputs the digital signal based on the reflected signal from the coupled selected antenna element.
