There are two basic types of radar: echo and Doppler. Echo radars work as described above. By obtaining data from two or more echo radars placed in different positions, it is also possible to capture additional information on an object’s position, such as its angle. A Doppler radar further enhances this capability by analyzing wave phases. It does this by keeping track of each particular wave and detecting differences in the position, shape, and form of the wave when it returns.
