Various embodiments relate to a radar system, including: a transmitter; a transmit antenna connected to the transmitter, wherein the transmit antenna is a circular polarized antenna; a receiver; a receive antenna connected to the receiver, wherein the receive antenna is a dual polarization antenna having a main lobe and ambiguity sidelobes; wherein the radar system is configured to: transmit a first and second radar signal with first and second circular polarizations in first and second modes; receive reflected first and second radar signals; process the received first and second radar signals to detect a target and to produce first and second mode target powers; comparing the first mode target power to the second mode target power to determine which lobe of the antenna in which the target is located.

Dual polarization radar

The disclosure relates to a doppler division multiplexing (DDM) multiple input multiple output (MIMO) radar system. Example embodiments include a DDM MIMO radar system () comprising: a transmitter () connected to a plurality of transmitter antennas () via a corresponding plurality of signal paths () of different electrical lengths (L) such that a phase of a signal transmitted by the transmitter () is different at each of the plurality of transmitter antennas ().

Radar system

In imaging radar, examples are directed to uses of multiple sets of transmit antenna included with transceiver circuitry, for transmitting in a plurality of modes. Transmissions may involve having at least one transmit antenna, from each of at least two of the multiple sets, to transmit continuous-wave energy concurrently (simultaneously) in one or more of the plurality of different modes. Transceiver circuitry may include multiple receive antennas which may be receiving reflections of the continuous-wave energy from various targets. Signals from the multiple receive antennas may route to signal processing circuitry. The signal processing circuitry may respond to the received reflections of the continuous-wave energy by assessing differences in antenna gain and/or phase due to transmit antenna position associated with the received reflections. This signal processing assessment may mitigate or resolve at least one spatial ambiguity in at least one direction of arrival dimension associated with the received reflections.
