In simple terms, it is a radar that steers its beam electronically by controlling many antenna elements, rather than steering the beam mainly by rotating or tilting the whole antenna mechanically. That is the defining idea. The radar face can remain fixed, but the beam can still be pointed in different directions.</p> <p>For beginners, this is the key contrast to remember. A conventional mechanically scanned radar usually points the beam by physically turning the antenna. A phased array radar points the beam by changing the relative phase of signals across an array of elements. NOAA&rsquo;s phased array radar explanations describe this directly: the antenna remains stationary while the beam can be steered electronically left-to-right and up-and-down.</p>
