Ground based radar systems are a critical resource to the command, control and communications system. This thesis provides the tools and methods to better understand the actual performance of an operational ground based radar system. This thesis defines two measurable performance standards: (1) the baseline performance, which is based on the sensor's internal characteristics and (2) the theoretical performance, which considers not only the sensor's internal characteristics, but also the effects of the surrounding terrain and atmosphere on the sensor's performance. The baseline radar system performance, often used by operators, contractors, and radar modeling software to determine the expected system performance, is a simplistic and unrealistic means to predict actual radar system performance. The theoretical radar system performance is more complex; but, the results are much more indicative of the actual performance of an operational radar system. The AN/UPS-1 at the Naval Postgraduate School was used as the system under test to illustrate the baseline and theoretical radar system performance. The terrain effects are shown by performing a multipath study and producing coverage diagrams. The key variables used to construct the multipath study and coverage diagrams are discussed in detail. The atmospheric effects are illustrated by using the Integrated Refractive Effects Prediction System (IREPS) and the Engineer's Refractive Effects Prediction System (EREPS) software tools to produce Propagations Conditions Summaries and Coverage Displays
