An overview of the studies on the FISST-based target tracking techniques is presented here. Special attention is paid to the following areas: optimal multi-target Bayes filter and its principled approximations,multi-target filter under unknown parameters, multiple maneuvering targets tracking, track-valued estimation, Joint Target detection and Tracking Filter (JoTTF) ,Bayesian filtering with random finite set observations, and also the relevant applications. Finally, based on the progress of existing research in these areas, some key issues to enhance the precision and robustness of target tracking further are introduced which deserve more attention of the researchers' for solution. These include: performance evaluation of multi-target filtering, dim/small target tracking,multiple maneuvering targets tracking,multi-sensor multi-target tracking, Joint target Detection,Tracking and Classification (JDTC) ,and so on.
