Hi Mehmet,
When you turn on Swerling mode in a radar target, you need to manage when to update the RCS in your simulation by passing in an additional logical flag to the step() call. If you pass in TRUE, then RCS will be updated, otherwise, the old RCS is used.
For example, let's say you have a Swerling II model and your are simulating one pulse a time, then in your loop, it will look like
for pulseIndex = 1:N
step(myTarget,x,true)
end
where N is the number of pulses you simulated and x is the signal.
On the other hand, if you have a Swerling I model which changes from dwell to dwell and assume each dwell is 10 pulses, then you will have something like
for pulseIndex = 1:N
if rem(pulseIndex-1,10)
step(myTarget,x,false);
else
step(myTarget,x,true);
end
end
If you need a system level example, you can take a look at the following shipping example which uses a Swerling II target
