    摘要: A MIMO radar transceiver assembly includes a plurality of transceiver circuit regions and a plurality of antennas. The plurality of antennas include a first transmit antenna coupled to a first transceiver circuit region among the plurality of transceiver circuit regions, a first receive antenna coupled to the first transceiver circuit region, a second transmit antenna coupled to a second transceiver circuit region among the plurality of transceiver circuit regions, and a second receive antenna coupled to the second transceiver circuit region. At least one of the second transmit antenna and the second receive antenna is interleaved between the first transmit antenna and the first receive antenna. Interleaving of the antennas can increase virtual aperture and angular resolution of the radar system without increasing physical dimensions of the transceiver assembly.

    摘要: Methods and systems for correcting leakage and/or distortion in radar systems include defining an integration time period, dividing the integration time period into a first sub-period and a second sub-period, at least partially transmitting a transmission radar signal during the first sub-period of the integration time period, not transmitting at all during the second sub-period of the integration time period, integrating the detected signal during both the first sub-period and the second sub-period, and subtracting a last sampled integrated value of the second sub-period from a last sampled integrated value of the first sub-period to generate a corrected integrated value for the integration time period.

    摘要: An apparatus for determining the position of a target object using a two-channel monopulse radar. The radar may include two transmitting antennas and one common receiving antenna disposed in a coplanar arrangement. The transmitting antennas may be positioned on the focal plane of the radar along a focal plane axis that extends through, and that is perpendicular with, a boresight axis of the radar. The transmitting antennas may be spaced apart from one another in a first dimension a distance equal to about one half of one wavelength of the radar's center operating frequency. One of the transmitting antennas may be squinted at an angle of θ1 relative to the boresight axis and the other transmitting antenna may be squinted at an angle of θ2 relative to the boresight axis in a second dimension. The transmitting antennas are not squinted relative to one another in the first dimension.

    摘要: A low profile antenna array for UWB radar antenna applications is disclosed. It may be used as a mid-range receiving antenna array (RXM) or as a mid-range transmitting antenna array (TXM). In some embodiments, the RXM or the TXM may include a plurality of radiation patch elements formed on a top layer of a printed circuit board (PCB), a distribution feeding network in the mid-layer of the PCB having a patch array, and a serial feeding arrangement from a λ/4 coupling slot to each feeding patch. This antenna may have a desirable large frequency bandwidth with relatively flat antenna gain over a frequency range from 22 GHz to 26.5 GHz. In addition, sidelobe levels for the elevation patterns may be below −20 dB. Other embodiments are disclosed and claimed.
