Math model building and echo simulation of chaff clouds jamming

To meet the increasing need of ballistic missile countermeasure, it becomes more and more important to study the feature of chaff jamming. Thus, the mathematical model of chaff cloud jamming is established, as a mathematical basis for simulation evaluation of chaff cloud echo. After analyzing the RCS based on incoherent scattering model and the statistical feature of chaff cloud echo, a new simulation method of chaff cloud echo is present, which is based on the ZNML. This method is easy to form fast algorithm , and its computation load is small.
