Hi,
Is it possible to simulate multiple targets in phased array toolbox such that a given target is completely obscured by the another? Essentially, what I am looking for is a way to not just get the reflected signal but also the transmitted signal that travels further in range and hits the another target and get reflected and so on.
Many Thanks

Yes, it's doable. The following example shows three targets in the same direction yet the return from all three are modeled.

Interesting! but it doesn't look like it compensate for the signal attenuation travelling through a target. It seems to treat each target as if the others are not present in the path. Am I right? To give you the context, I am looking at a target behind a wall so the first reflection would be from the wall itself (wall clutter in this application) then a much attenuated signal propagates to the actual space of interest (behind the wall). Could this be simulated in any way?

Thanks for the clarification. The attenuation is currently not simulated. As a rough workaround, would it be possible that we first compute the attenuation and then manually apply it to the signal?

good idea. thanks I will try that out.
