Abstract:
Radio Detection and Ranging (RADAR) is a technology with which immense practical consequences can be measured and detected at high accuracy. Using radar, Air travel is thousands of times safer than travel by road, astronomers can map the contours of far-off planets, physicians can show images of internal organs, meteorologists can measure weather change in distant places on Earth. Due to its reasonable larger practical applications, the bistatic radar cross section of F117 Nighthawk Stealth Aircraft is the main focus of our thesis.
The main goal of this thesis is to carry out a detail study of the Radar Cross Section with an aim to find out its performance under changing radar transmitter’s frequency variation, aspect angle configurations. In this regard, various radar parameters were swept and the best outcome was identified. Thereafter, the significant effect of radar frequency and aspect angle on F117 Nighthawk in its RCS were studied with a small introduction to complex target RCS. The significance of operating frequency and aspect angle on radar detection range has also been illustrated.
An elaborate and exhaustive effort is taken to examine various antenna parameters to suggest the best possible radar configuration for better target detectability. In this regard, various correlated mathematical equations were taken into consideration, those were simulated using COMSOL Multiphysics to provide relevant plots for study and analysis. The extensive use of this toll has made the thesis extremely interesting with valuable results drawing important conclusions about the behavior of radar under changing conditions.
