Multipaths represent a common predominant and uncontrolled component on channel impairments for all terrestrial and Land Mobile Satellite systems. Without restrictions w.r.t mobile terrestrial applications, the addressed multipath problematic in this paper is focused on Land Mobile Satellite applications where delayed signal replicas are highly impacting performances on communication systems while they induce strong positioning errors for navigation systems. The actual trend in propagation channel modelling is to improve the multipath characterisation and representation by using semideterministic and hybrid physical-statistical models into channel simulators instead of narrow-band empirical approaches. In this context, this paper presents a new simplified model, called 3CM (3-Component Model) to reproduce building scattering in an efficient way which strongly improves computation performances. This model is based on asymptotic methods, namely, PO (Physical Optics) which allows the 3CM to be frequency scalable, polarimetric, and dielectric materials oriented. Note that the proposed model and the retained approach can be integrated into more complex tools such as existing ray tracers. However, this issue is not discussed in this paper.

Guidance of weapon systems relies on sensors to analyze targets signature. Defense weapon systems also need to detect and then identify threats also using sensors. One important class of sensors is radar systems that are very efficient for all weather detection. High frequency radars can produce high quality images with very complex features such as dihedral and corner reflector high scattering contributors, shadows and layover effects. Besides, image quality is very dependent on the carrier velocity and trajectory. Such sensors systems are so complex that they need simulation to be tested in a large variety of operational conditions. This paper presents a state-of-the-art solution, called SE-Workbench-RF, for generating raw data dedicated to radar simulation based on the exploitation of synthetic environments, which means physical modelling of targets and backgrounds (terrains, buildings, vegetation and other entities). The paper gives an overview of the models and their implementation in SE-RAY-EM, which is the rendering module of SE-Workbench-RF, including specific features related to radar simulation in the maritime environment with targets moving on the dynamic sea surface. Several technical topics are then discussed, such as the rendering technique (ray tracing vs. rasterization), the implementation (CPU vs. GP GPU) and the tradeoff between physical accuracy and computational performance. Finally, typical examples of results are shown both in the frame of Synthetic Aperture Radar sensors and Real Beam Ground Mapping radars.
