matlab实现NNSF

数据互联算法。绘制出了目标真是轨迹、测量轨迹、PDAF估计轨迹和NNSF估计轨迹，并进行了对比分析。-Data Association Algorithm. Drawn out of the goal really track the trajectory measurements, PDAF estimated trajectory and NNSF estimated trajectory, and a comparative analysis.

利用最近邻域标准滤波器（NNSF）和概率数据互联滤波器（PDAF）进行航迹绘制并进行相互比较。-Use nearest neighbor standard filter (NNSF) and probabilistic data association filter (PDAF) be drawn and compared with each other track.
