This paper introduces the assimilation technology in an ocean dynamics model and discusses the feasibility of inverting the sea surface current in the detection zone by assimilating the sea current radial velocity detected by single station HF ground wave radar in ocean dynamics model. Based on the adjoint assimilation and POM model, the paper successfully inverts the sea surface current through single...
Signal level simulation is necessary to improve the fidelity of radar signal processing simulation, however the computation loads are too high for a CPU based platform. Compute Unified Device Architecture (CUDA) provides a new way to implement signal level simulation on a cost effective device. In order to compare the performances of signal level simulation based on Graphic Processor Unit (GPU) and...
With the requirement of surface current extraction by a single station of high frequency surface wave radar, high frequency SAR (HF-SAR) is proposed and proved to be theoretically feasible. However the old model of HF-SAR is not perfect enough and there are several drawbacks such as Bragg scattering not included, high computation burden and implementation difficulty. Thus in this paper we present...
To meet the requirement of extracting sea surface current information by a single station, we present the new concept of high frequency SAR (HF-SAR), and consider the feasibility of extracting sea surface current by HF-SAR. Firstly the implementation aspects are described, then system model and velocity estimation algorithm are designed, and finally simulation model to extract surface current is implemented...
On the requirement of extracting sea surface current information by a single station, we try to apply synthetic aperture technique to HF surface wave radar, present the new concept of HF surface wave SAR (HF-SAR), and consider the feasibility of extracting sea surface current by HF-SAR in this paper.
