“What is out there that cannot be seen?” This question is asked by many in the scientific and infrastructure communities, and the solutions typically include IR, ultrasound, and radar imaging; individually or a combination of sensors to provide a “picture”, “map” or “image” of the unknown.
Automotive radar, utilizing small, low cost, low power (24 to 77 GHz) and mass
produced sensors are common-placed commercial applications of FMCW radar
today. When used in combination with other sensors, autonomous driving vehicles will
also become common-place within the next few years.
