摘要： A mechanism is provided for estimating mounting orientation yaw and pitch of a radar sensor without need of prior knowledge or information from any other sensor on an automobile. Embodiments estimate the sensor heading (e.g., azimuth) due to movement of the automobile from radial relative velocities and azimuths of radar target detections. This can be performed at every system cycle, when a new radar detection occurs. Embodiments then can estimate the sensor mounting orientation (e.g., yaw) from multiple sensor heading estimations. For further accuracy, embodiments can also take into account target elevation measurements to either more accurately determine sensor azimuth and yaw or to also determine mounting pitch orientation.

摘要： A first-transceiver system for use in an antenna diversity scheme. The first-transceiver system comprising: a first-receiver; a first-time/clock-generation-unit; a first-transmitter; and a timing-controller. The first-receiver is configured to receive a wireless first-common-signal from a third-party-transmitter, wherein the first-common-signal is representative of a common-signal transmitted by the third-party-transmitter. The timing-controller is configured to: receive signaling representative of the first-common-signal; receive signaling representative of a wireless second-common-signal as received at a second-transceiver, the wireless second-common-signal being representative of the common-signal; and generate a timing-signal based on the first-common-signal and the second-common-signal. The first-transceiver system is configured to set the first-time/clock-generation-unit, based on the timing-signal, to reduce an alignment-error between the first-time/clock-generation-unit and the second-time/clock-generation-unit. The first-transmitter is configured to transmit a wireless first-transmission-signal, in accordance with the first-time/clock-generation-unit, as part of the antenna diversity scheme that comprises aligned transmission of both the first-transmission-signal and a second-transmission-signal.

摘要： A first-transceiver for use in an antenna diversity scheme. The first-transceiver comprises a first-time/clock-generation-unit; a first-receiver; and a first-transmitter. The first-receiver is configured to receive a wireless second-alignment-signal from a second-transceiver with a second-time/clock-generation-unit. The wireless second-alignment-signal is representative of a state of the second-time/clock-generation-unit. The first-transceiver is configured to set the first-time/clock-generation-unit, based on the wireless second-alignment-signal, to reduce an alignment-error between the first-time/clock-generation-unit and the second-time/clock-generation-unit. The first-transmitter is configured to transmit a wireless first-transmission-signal, in accordance with the first-time/clock-generation-unit, as part of the antenna diversity scheme. The first-transmission-signal corresponds to a second-transmission-signal that is transmitted by the second-transceiver. The antenna diversity scheme comprises aligned transmission of both the first-transmission-signal and the second-transmission-signal.
