“…As a result, a focused SAR image is created. The described algorithm has been verified by the authors using simulations [7] and several different trials with various SAR systems [4,5,6]. The first results of using the developed algorithms for the proposed USRP based SAR system are shown in the next section.…”

The paper presents a concept of using universal software radio peripheral (USRP) as a hardware platform for frequency modulation continuous wave (FMCW) synthetic aperture radar (SAR). The concept presented has been successfully verified through several measurements in the laboratory, as well as in real scenarios where the USRP-based SAR radar was mounted on a ground moving platform and SAR images of the surrounding area were created. The results obtained show that USRP hardware can be used successfully in low cost SAR projects, as well as a system for testing FMCW analog front ends. Moreover, due to its small size the proposed system can be used as a direct digital synthesizer (DDS) and analog digital converter (ADC) for low cost systems dedicated for small ultralight aircrafts or medium size unmanned aerial vehicles (UAV).

“…There are 2 main approaches for simulation: image simulation and raw data simulation . The former is faster but it doesn't generate the backscattering field data and it cannot be used for developing the processing algorithms . However, the latter is based on the simulation of backscattering field.…”

An efficient algorithm is proposed to simulate the backscattering field of a complex marine target and surrounding 3D sea surface as clutter. Sea surface backscattering is simulated based on the numerical solution of the Electric Field Integral Equation by an improved meshing algorithm. The complex target is modeled using the discrete scattering centers independently. Combining the target and sea surface backscattered fields is used to extract the SAR raw data. The effectiveness of the proposed algorithm is verified for 2 hypothetical cases.
