Advances in Radar Systems for Modern Civilian and Commercial Applications: Part 1 [From the Guest Editors]

The articles in this special section focus on advancements in radar systems for current commercial applications. Radar was developed during World War II for defense and security applications, and it was initially used for detecting aircrafts and missiles, replacing short range and narrow field of- view acoustic devices. This special section is part of a two-part series. The goal of both parts is to show the main techniques applied in different scenarios by different systems, focusing particularly on some of the new civil and commercial applications. There are, however, no articles dedicated specifically to defense, harbor, or airtraffic control nor on long-range remote sensing.
