Simulation of a radar in Flames: a ray based radar model
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
In this report a radar model is modeled and implemented in a simulation framework
called Flames. The focus is to investigate how and if electromagnetic waves emitted
from the radar antenna can be simulated by different methods and how these
methods can be implemented to work in real-time simulations. The radar model
developed in this report is based on ray tracing and ray propagation techniques
developed by the author. The model considers varying refractive indices that
describes both standard atmospheres and atmospheres where ducting occur.
Preparatory studies are also made to model ground reflection by ray tracing
techniques. Other simulation techniques, such as the Finite-Difference Time-Domain
method and the Split-Step Parabolic Equation method, are furthermore considered
for radar simulation applications. The results show that ray tracing in conjunction
with geometrical optics is a valid method for simulating electromagnetic waves in
simple atmosphere models.
