Abstract: An antenna apparatus and a method of operating the antenna apparatus can include a group of receive antenna elements and a transmit antenna array comprising transmit antenna elements, wherein the transmit antenna array is located centrally in a phased array aperture that includes the transmit array antenna and the plurality of receive antenna elements. An isolation area can isolate the transmit antenna array from the receive antenna elements in the phased array aperture, and the phased array aperture can operate with a hybrid dual mode comprising a radar mode and an active beaming steering mode. The radar mode can be a multiple input multiple output (MIMO) radar mode, and the beamforming mode can be an antenna beamforming mode.

Abstract: A retrofit system applied to existing FMCW radars in order to convert them into pulsed linear frequency-modulated radars with the ability to dynamically switch between two pulsed modes and an FMCW mode based on the estimated range of a target. This retrofit also includes provisions for adaptively configuring chirp and sweep parameters to optimize range resolution. The result is a retrofit system capable of converting an FMCW radar into a dual pulsed mode radar with adaptive sweep configuration.

Abstract: A two-dimensional phased subarray MIMO radar apparatus includes a transmission array and a reception array. The transmission array is configured to emit transmission signals, which are orthogonal to each other, towards a target object and extends in a first direction. Moreover, the transmission array includes a plurality of transmission phased subarrays. The reception array is configured to receive reflected signals, which are reflected from the target object, among the emitted transmission signals and extends in a second direction intersecting the first direction. Moreover, the reception array includes a plurality of reception phased subarrays. Each of the plurality of transmission phased subarrays includes a plurality of transmission antennas. Each of the plurality of reception phased subarrays includes a plurality of reception antennas. A first transmission phased subarray and a second transmission phased subarray are adjacent transmission phased subarrays among the plurality of transmission phased subarrays. A spacing from an end of the first transmission phased subarray in the first direction to an end of the second transmission phased subarray in the first direction is a first spacing. The first spacing is greater than or equal to an aperture of each of the plurality of transmission phased subarrays.
