Simulation of radar observation of a sea patch using the TLM electromagnetic method

Résumé

We propose the simulated rendition of the observation of a variety of small sea patches by radar. These patches include a random sea surface of variable state, with possibly the presence of a manufactured, metallic object in its middle. The simulation in itself draws upon two different techniques which are combined: for the free-space propagation, a simple geometrical ray tracing method is used. On the other hand, we rely on a discrete calculation of the propagation of the electromagnetic waves in the vicinity of the sea surface, using the TLM method. Different aspects of this particular electromagnetic method are discussed in this paper. The originality of the approach is the combination of a geometrical calculation with a discrete, exact computation, each of them being devoted to a precise part of the simulation. Further matter in the article extends onto the explanation of some techniques developed for the need of our study, presentation and annotation of some results along with computation times, and overall discussion.
