A radar is designed to transmit electromagnetic energy in a format that permits the extraction of information about the target from its echo. Once a target is detected, the next goal is often to precisely locate that target in three-dimensional space, which requires accurate measurements of the distance and angle (both azimuth and elevation) to the target. In addition, it is often desirable to estimate the radar cross section (RCS) and radial velocity of the target as well. In this chapter, some of the common techniques for radar measurements are described, along with factors determining their accuracy and precision. Space limitations preclude considering additional techniques and error sources.
