Abstract: A multiple input multiple output (MIMO) antenna for a radar system includes a receive antenna, a first transmit-antenna-arrangement, and a second transmit-antenna-arrangement. The receive-antenna is configured to detect radar-signals reflected by a target toward the receive-antenna. The first transmit-antenna-arrangement includes a first vertical-array of radiator elements and a second vertical-array of radiator elements. The first transmit-antenna-arrangement is configured so the first vertical-array can be selectively coupled to a transmitter independent of the second vertical-array. The second transmit-antenna-arrangement includes a third vertical-array of radiator elements and a fourth vertical-array of radiator elements. The second transmit-antenna-arrangement is configured so the third vertical-array can be selectively coupled to a transmitter independent of the fourth vertical-array. The second transmit-antenna-arrangement is vertically offset from the first transmit-antenna-arrangement by a vertical offset distance selected so an elevation angle to the target can be determined by the receive-antenna.

Abstract: A Pseudo-Random Phase Modulation (PRPM) multiple-input-multiple-output (MIMO) radar system suitable for use on an automated vehicle includes a first transmit-antenna that transmits a first transmit-signal generated by a first PRPM-code, a second transmit-antenna that transmits a second transmit-signal generated by a second PRPM-code, a receive-antenna used to detect a first reflected-signal arising from the first transmit-signal and a second reflected-signal arising from the second transmit-signal, and a controller. The controller is in communication with the receive-antenna and is operable to generate the first PRPM-code and the second PRPM-code. The controller is configured to generate a first sub-channel-output based on a down-converted-signal from the receive-antenna and the first PRPM-code, generate a second sub-channel-output based on the down-converted-signal from the receive-antenna and the second PRPM-code, determine a first residue-signal based on the second sub-channel-output, and determine a first residue-removed-signal by subtracting the first residue-signal from the first sub-channel-output.
