The first radar was patented 110 years ago. Fast forward to today, radar applications have become ubiquitous in typical applications i.e. speed control, air traffic control, airborne and space-borne missions, military applications and remote sensing. Research for medical radar applications is also progressing well for breast cancer detection and tumor localization. Automotive radar for safety and autonomous driving are meanwhile being produced in millions per year. Despite the significant technological advancements the radar system technology unfortunately did not evolve like the communications and other related technologies for the last 20 years. With the development of high-speed electronic devices and higher demand for radar systems, the current state-of-the-art radar system concepts will undergo a revolution. They will be conceptualized and integrated in the current radar technologies leading to revolutionary radar systems. This will ultimately lead to new radar features and radar signal processing.
