Todays, Chaff as one of the most effective techniques of electronic warfare, has a particular importance. It is difficult to study the behavior of chaff, because of the impossibility of chaff tests in an unechoic chamber. Therefore, the simulation would be a suitable alternative and have importance role for study of its behavior. In this paper, By considering conventional radar, the modeling and simulation of various features of sea chaff for search and tracking modes are performed. For radar search mode, six-dimensional spaces (6Ds) including: The RCS (Radar Cross Section) fluctuation, doppler width, symmetry and sparsity in range axis, polarization effect and standard deviation in range axis have been considered. But for radar tracking mode, modeling and simulation of the process noise in the 1D dimensional space, along with the Kalman prediction covariance matrix has been accomplished. The suggestion to use of process noise as a distinctive feature of the target from chaff is the innovation of this paper. In addition, considering the radar search mode, modeling and simulating its features in various spaces are other achievements of this article.
