Medium PRF set selection based on IGA

As Pulsed-Doppler radars can detect target from background of very large clutter beam,they have been widely used.But there are unavoidably blind regions in range and velocity.So,a set of PRFs need to be selected to resolve ambiguity.Immune Genetic Algorithm(IGA)is based on immune theory.It's the improvement of GA,and conquers GA's disadvantage such as:premature,low efficiency of perform and less individual diversity.This paper selects multiple PRFs using IGA,based on real coding.The experiment shows that this method turns out to be convenient for coding and finding optimal solutions more accurately than general GA.
