This week, National Instruments (NI) announced a technology demonstration of a test system for 76-81GHz automotive radar, targeting ADAS (Advanced Driver Assistance Systems) applications. The system is based on the company’s mmWave front-end technology and its PXIe-5840 2nd-generation vector signal transceiver (VST), introduced earlier this year, which combines a 6.5GHz RF vector signal generator and a 6.5GHz vector signal analyzer in a 2-slot PXIe module. (See “NI launches 2nd-Gen 6.5GHz Vector Signal Transceiver with 5x the instantaneous bandwidth, FPGA programmability.”) The ADAS Test Solution combines NI’s banded, frequency-specific upconverters and downconverters for the 76–81GHz radar band with the 2nd-generation VST’s 1GHz of real-time bandwidth.
The PXIe-5840 VST gets its real-time signal-analysis capabilities from a Xilinx Virtex-7 690T FPGA.
