鉴于网上合成孔径雷达的资料比较少，上传一些老师给的文献资料，希望对大家有帮助(Given the online synthetic aperture radar data is relatively small, upload some literature teacher, I hope to help everyone)

卡尔曼滤波扩展程序代码，很好的程序，大家都来下载吧！赶紧的！(Extended Kalman filtering code, very good program, we have to download it! Hurry it!)

Under the circumstances of pure lag in feedback control system and the imprecision of the controlled object model, the fuzzy logic and pure lag compensation theory is used to design a Fuzzy PI-Smith control system . By the Simulink toolbox and Fuzzy logic toolbox of MATLAB, the system has been simulated. The simulation results show that the Fuzzy PI-Smith system has faster response speed and smaller overshoot than the traditional PI-Smith system.The explicit formulation of Fuzzy PI-Smith system is derived, and it lay the basis for the practical application of control algorithms.
