FDTD的MATLAB代码，二维成像模型(FDTD MATLAB)

这是一本很少见的中文matlab帮助手册，特别对于点运算等入门级知识进行了详解，大家共享吧！(This is a very rare Chinese matlab help manual, particularly for entry-level point of computing, such as the detailed knowledge, share it!)

I found this paper regarding to LPR interesting and I would like to share it.

基于粒子滤波的雷达检测前跟踪算法，建立新的目标模型和观测模型，提出了线性扩展目标。能够检测1db的弱小目标。(A radar target track-before-detect (TBD) algorithm using particle filter (PF) is presented in this paper. System dynamic model and measurement model are established based on a sequence of radar range-Doppler measurements using the new algorithm. Furthermore, a linear xtended target model is proposed, which is more capable of describing a maneuvering target than the conventional point arget model. The likelihood ratio function of the new model is also derived in this paper. Due to the accumulation of the PF-TBD over time and the effectiveness of the proposed target model, an mproved probability of detection for dim target is obtained. The experimental imulations demonstrate that the proposed method is capable of detecting and tracking a target with SNR of 1 dB robustly. )
