波数域算法又称为距离徙动算法（Range Migration Algorithm，RMA）或-算法，由Cafforio等提出。该算法分析距离处理后信号的二维频谱，通过二维频域匹配滤波进行相位补偿，在完成方位聚焦的同时完全校正距离徙动。由于其中的Stolt变换能克服SAR信号中距离徙动和SRC对斜距的依赖，因此波数域算法是一种理想的成像算法，尤其在处理大斜视角和长合成孔径的SAR数据时。但Stolt变换需要插值，降低了处理效率并引入额外的误差。(The wavenumber domain Algorithm is also called Range Migration Algorithm (RMA) or -algorithm, which is proposed by Cafforio et al.The algorithm analyzes the 2-d spectrum of the signal after the distance processing, carries out phase compensation through the 2-d frequency domain matching filter, and completely corrects the distance migration while completing the azimuth focusing.Because the Stolt transform can overcome the SAR signal range cell migration and SRC dependence on oblique distance, thus wavenumber domain algorithm is an ideal imaging algorithm, especially when dealing with large squint Angle and long synthetic aperture of SAR data.But Stolt transformation requires interpolation, reduces processing efficiency and introduces additional errors.)

matlab编写的粒子滤波算法，已经在工程样机上得到验证，希望对大家有帮助(matlab prepared particle filter algorithm, the engineering prototype has been tested on, and they hope to have everyone help)

Goal of the project was to use numerical methods for solving systems of ordinary differential equations (ODE) using MATLAB software. As in previous assignments first of all I had to research for algorithms, which would be helpful during evaluation of each task, later on I was able to implement and test numerical methods for solving given problems. Each student received electric circuit containing different elements to solve. Each task is presented under separated heading, with its full description, problem discussion, my approach for solving it and explanation.
