Radar Echo Simulation of Large Scenes Using Domain Decomposition Method

Accurate radar echo simulation is a key part in analyzing the performance of radar signal processing algorithms. However, it has some bottlenecks for large scene radar echo simulation, such as high memory and time complexity of existed algorithms. In this work, we take advantage of the domain decomposition method to simulate the radar echo of large scenes. The original scene can be divided into some independent domains adaptively using our algorithm. The coupling among each domain can be eliminated after the process. Numerical results show the accuracy and efficiency of such method.
