Xcerra Kestrel/X-Series Measures Automotive Radar Chirp Linearity

Abstract:

Collision avoidance radar devices generate bursts of RF energy called ‘Chirps’. Which are transmitted (TX) to be reflected and ultimately received (RX). A Chirp is a sinusoid that increases its frequency linearly. The linearly changing frequency of each chirp can be used to extract vector speed information about the target. EBand Radar devices produce chirps over a bandwidth of 1GHz and, as in this example, near 76GHz.
