Abstract :
Modern radars have evolved greatly from their origins as providers of blips and blobs to highly trained operators in darkened rooms. Today, all-weather, day and night radars provide clear digital images as detailed and useful as photographs. They also provide digital symbolic representations of multiple types of air, sea, and ground moving targets over wide geographic regions. Today´s state-of-the-art radars can even provide flexible, on-demand sensing services to a large network of users. This tutorial will introduce the student to both the physics and the digital technology underpinning modern radars. The first half of this tutorial will describe how radars detect and image objects in their field of view. The second half of the tutorial will describe how radars estimate and predict the behavior of those objects.
