I am working on the system model of an impulse radar. My primer aim is to simulate the received signal. I use signal components and some simple elctrical circuits in the Maplesim model. First version of the system works fine, but I'd like to develop it.
I have the following problems:
- I don't find a way to put a time-delay in the system (in time-domain or in s-domain in the form of' *exp(-s*T)' )
- It seems to me that there is no direct way to add noise to the system (like Gaussian...)
- It would be useful to have a direct way to see the spectra (FFT) at a given pont of the system. For example an FFT probe or probe with option for FFT.
Thansk for help in advance.
