ii have a problem in matlab phased array system tool box (end to end radar system)?

i have a problem so please if any one can help me:

1- i work in radar detection

2- my supervisor asked me to get a real signal for (radar echo signal) have all parameters of radar system so i can change any parameters to catch all cases in my study of detection

3- i found that the end to end radar system model from phased array system tool box has most of radar parameters so i suggested to work on the reflected signal from this model(rxsig) to apply a new method for detection on this signal

4- the problem that was faced me is how to make RCS changeable with (frequency - aspect angle - polarization) specially polarization

5- i tried to see matlab help to do the RCS step function with polarization enable but i have an error

6- this is my target

htgt = phased.RadarTarget('Model','Nonfluctuating','EnablePolarization',true,'Mode','Monostatic','ScatteringMatrixSource','Property','ScatteringMatrix',[1 0;0 1],'PropagationSpeed',physconst('LightSpeed'),'OperatingFrequency',4e9);

7- so i want to make step function for this target

8- and also i want your advice if i'm in the right way or not thank you very much

How do you want your RCS change? Do you have a model or a data matrix specifying the RCS in different frequency and aspect angle? How big is that data matrix?

Currently Phased Array System Toolbox's RadarTarget does not support specifying RCS using a data matrix or file. The support of RCS variation is via Swerling models.

However, you can always write your own function to achieve this and simply replace the step() call to the target in the simulation. Essentially, you need to compute the RCS for each hit and then compute the reflected signal.

thank you for your answer i want to change RCS according to change of polarization of th incedent wave and receiving antenna polarization for any target not a specific data

I need Phased Array System Toolbox for my research. When i try to get trial version, Mathworks say, "Phased Array System Toolbox is not available". I cannot find trial version of this toolbox. Any help?
