This project mainly deals with the detection problem for non-independent identically distributed (non-iid) targets. The detection theory for non-iid targets can be established and improved by investigating the following fundamental problems: the electromagnetic scattered principle of non-iid targets, the fluctuating model,correlated model and calculation of statistical functions (i.e. joint probability density function (pdf) and the pdf of random variable sums), the optimal detection algorithm and performance evaluation. We will propose the detection strategies for non-iid targets, provide the corresponding design approachs, solve the key technologies, and devise the simulation experiments to validate the presented the theory results. The research of this project is of great significance, since it can improve the fundamental research levels and the innovational abilities of our country for detecting the complex fluctuating targets. Moreover, the theory results can be applied directly to frequency agility radars, MIMO radars, high resolution radars and polarimetric radars.
