Automotive mmWave Radar Test Solution

Automotive radar applications are part of Advanced Driver Assistance Systems (ADAS) for both manned and autonomous vehicles.

This Automotive mmWave Radar Test Solution allows to generate and analyze multichannel Frequency Modulated Continuous Wave (FMCW) radar waveforms for complete component, subsystem, and system performance at baseband, IF, and millimeter-wave (mmWave) 24 GHz, 77 GHz and 79 GHz bands.

This Compact Reference Solution combines COTS modular hardware and software from Guzik, Keysight Technologies and Virginia Diodes, which provides a flexible testbed for FMCW radar waveform generation and analysis. The test setup allows to de-embed external cables, attenuators or amplifiers in front of the digitizer with Guzik patented FPGA-based interleaved ADC amplitude and phase response equalizer.

Software provides the flexibility to generate and analyze FMCW waveforms with a wide range of different attributes.

Modular hardware provides the flexibility to support baseband, IF, and millimeter-wave test planes.

Frequencies up to 10 GHz can be supported with the base test equipment configuration for testing with a wide range of IF’s and the 22.5-40 GHz industrial, scientific and medical (ISM), 5 GHz wide ultrawide band (UWB) band and 60-90 GHz shortrange radar (SRR),  long-range radar (LRR) band frequencies can be generated and analyzed with the Virginia Diodes compact up-converters and down-converters.

This Reference Solution can be used as an independent reference to help debug and validate hardware performance issues as they occur.
