Abstract: A method of operating a radar system includes transmitting a plurality of transmitted radio frequency (RF) signals by a plurality of directional antennas. The plurality of directional antennas is disposed on a planar surface of a substrate. Each of the plurality of antennas is in a fixed orientation and position on the planar surface. A respective individual coverage of each of the plurality of directional antennas is less than 360°. A combined coverage of the plurality of transmitted RF signals completely covers a 360° region surrounding the radar system. The method also includes receiving a reflected RF signal by a directional antenna of the plurality of directional antennas.

Abstract: In accordance with an embodiment, a method of operating a radar system includes receiving radar configuration data from a host, and receiving a start command from the host after receiving the radar configuration data. The radar configuration data includes chirp parameters and frame sequence settings. After receiving the start command, configuring a frequency generation circuit is configured with the chirp parameters and radar frames are triggered at a preselected rate.

Abstract: A radio frequency (RF) system includes an RF integrated circuit (IC) die. The RF IC die includes a first transmit circuit, a second transmit circuit, a first receive circuit, a second receive circuit, and a control circuit coupled to the first transmit circuit, the second transmit circuit, the first receive circuit, and the second receive circuit. The RF system further includes a first antenna coupled to the first transmit circuit and the first receive circuit using a first coupling structure. The control circuit is configured to activate the first transmit circuit and deactivate the first receive circuit during a first operation mode. The RF system further includes a second antenna coupled to the second transmit circuit and the second receive circuit using a second coupling structure. The control circuit is configured to activate the second transmit circuit and deactivate the second receive circuit during a second operation mode.
