Development of Modeling & Simulation Tool for Long Range Radar Considering Operational Environment in Time Domain

The performance of long range radar is affected by the atmospheric conditions and terrain, as well as the beam operation of the radar system. In this paper, a modeling and simulation(M&S) tool was developed considering the external environment and radar systems of long range radars for performance prediction, and was described using the verification method. Atmospheric refraction and wave propagation were simulated using APM, to analyze the effects of the external environment. The beam template of radar, which is used for actual radar systems, was utilized to analyze the effects of beam operation. The developed M&S tool was verified by comparison with the experimental results obtained from three different situations and confirmed to be highly effective in predicting the performance of long range radar.
