The GPU computing has recently opened news efficient ways for radar simulation. For small target detection and for advanced processings such as imagery SAR/ISAR, the simulation of realistic raw data is crucial. It concerns maritime patrol applications from unmanned and manned platforms, such as presented in [1]. The aim of this paper is to present works driven by DGA and to illustrate the recent progress...
Known as a useful tool to simulate SAR image, the MOCEM software has been recently extended. Now, its version 4 includes new features to simulate the radar raw data of a maritime scene composed of a ship on a dynamic sea surface. This paper describes the latest developments of the software and illustrates the work done in the context of a cooperation involving FFI (Norway) and DGA MI (France). Thanks...
Compressed sensing (CS) is a new theory that enables sampling below the Nyquist rate, while the quality of reconstruction is guaranteed. This theory is applied to sparse circumstance. Based on this theory, this paper proposes a feasible method for the spaceborne stripmap synthetic aperture radar (SAR) raw data imaging. The technique presented is introduced as an alternative option to the traditional...
A novel simulator is presented for interferometric synthetic aperture radar (InSAR), which contains three simulation levels: the raw signal level (RSL), the SLC image level (SIL) and the interferometric phase level (IPL). In this simulator, a new model of complex backscattering coefficients for the extended scene with low complexity is presented and validated. Furthermore the implementation details...
Employing three-dimensional mapping and projection algorithm (MPA), imaging simulation of bistatic SAR (BISAR) observation over complex scenario is developed. Based on the explicit expression of point target response of stripmap BISAR imaging, raw data is efficiently generated from the scattering map pre-calculated by MPA. Some examples of BISAR image simulation are studied. Polarimetric characteristics...
