Research on Variation of Detection Performance according to Altitude of Radar by Using Modeling and Simulation Method

The performance of a radar is affected by the operating conditions as well as radar systems(radar specifications). Atmospheric refraction and terrain are typical conditions of operation. The operating conditions depend on radar location. In particular, the detection performance of a radar is greatly affected by altitude. If the radar altitude gets higher, the radar can have good environment of radio wave at far range. Radar performance can also improve when the beam steering angle is properly adjusted. In this paper, we conducted research on the relationship between radar altitude and the beam steering angle, and variations in the detection performance of the radar. By using modeling and simulation methods, we developed a model by considering the external environment and radar systems to analyze the detection performance of the radar.
