Cognitive radars in spectrally dense environments

Radar technology has been evolving towards higher resolution, high-precision detection instruments with an ever-increasing list of functionalities. One of the areas, which have very good potential for combining the benefits of these developments, is multifunction radar systems. These systems perform multiple functions simultaneously, including surveillance, tracking, confirmation of false alarm, backscanning, clutter, and interference cancellation, which are traditionally performed by dedicated individual radars. With the introduction of these new radar requirements, future radar systems will need to work with wider frequency bands than traditional radar systems.
