Since radio waves and alternating current (ac) signals are vital to all radar functions, any introduction to radar logically begins with them. Indeed, many radar concepts which at first glance may appear quite difficult are simple when viewed in the light of a rudimentary knowledge of radio waves and ac signals. In this chapter we will consider the nature of radio waves and their fundamental qualities.
