SAR imaging of complex environments with EMPRISE® simulation software

Abstract:
The development of modern radars relies on digital simulation for their design, evaluation, and qualification. Additionally, simulated SAR data facilitates the development and improvement of processing methods. In this context, ONERA is developing the EMPRISE(r) tool in partnership with SCALIAN-DS, under the supervision of DGA-MI. This paper explains the employed standards, methodologies, and simulation strategies for efficiently simulating radar signals and SAR images of acquisitions over vast real-world terrains and varied environments. A real measurement is compared with the results for our transfer function method and the simulation of the focused complex raw data.
