Description

This automotive radar is a cascaded 76GHz to 81GHz radar sensor module. This includes two-device cascaded array of AWR2243 devices and an AM2732R radar processor. In this cascaded radar configuration, a primary device distributes a 20GHz local-oscillator (LO) signal to both the primary and secondary devices, allowing these two devices to operate as a single RF transceiver. This enables support for up to 6 transmit (TX) and 8 receive (RX) antenna elements, giving a total number of 48 virtual channels in the MIMO virtual array.
