1.4. Radar waveform
The ScanBrick® W system transmits a FMCW signal in automotive band. At receiver stage, matched
filtering is performed via a mixing stage of received signal with a copy of the transmitted one. Such
an operations, also known as “dechirping” provides an IF signal which frequency components are
directly related to the targets distance. The signal is sampled and sent to host via Ethernet link.
The transmitted signal parameters are defined in Tab.2.
