I'm trying to analyze the probability of detection ($P_d$) for a Swerling II target. I know that the Swerling II target assumes that the Radar Cross Section (RCS) is an exponential probability density function, and that the RCS fluctuates from pulse-to-pulse.
My question is: Do the Swerling models assume perfect decorrelation from pulse-pulse? As in, do they assume that the RCS on each pulse is purely independent of other pulses, or do they account for some correlation?
The target I'm trying to analyze does not perfectly decorrelate between pulses. So, the RCS on pulse #2 will be somewhat correlated to that on pulse #1.
