Possible to obtain bistatic clutter model?

Howdy!

The "constant gamma clutter" model states that it assumes the radar is monostatic. http://www.mathworks.com/help/phased/ref/phased.constantgammaclutter-class.html

How can I make a clutter model, for a Bistatic radar?

I have tried to look through the step() of the phased.ConstantGammaClutter object, in ConstantGammaClutter.m in the MATLAB install directory, and found the protected method stepImpl().

Unfortunately, all the variables are private, and there are so many levels of functions that it's hard to find out what's actually going on.

I understand that, in a bistatic case, the clutter is being reflected at different angles. This probably means it is more computationally intense than the monostatic case that is already provided. Is there anything from MathWorks that can help me with this?

Since the question asked and the answer posted here was in 2015, so asking again:

In the latest Matlab releases, has anything been included to model bistatic clutter?

Answer 1

Unfortunately there is no bistatic clutter model in Phased Array System Toolbox at this point. Is there any particular model you are interested in? Like you mentioned, the bistatic clutter computation can be quite intensive.

Honglei, thank you for your prompt response!

Basically the constant gamma clutter model assumes the radar is monostatic, and is at a constant speed & height. So for example, it could be an aircraft moving in a straight line, and I choose any terrain gamma value I want.

My desired changes for Bistatic do not affect the Receiver constraints; I just want to place the Transmitter elsewhere in space.

Thanks Chris, I'll take a look.

It appears that most researchers are simply creating their own Clutter models in MATLAB, to fit their specific needs.

Here is one example, where they're specifically using the Phased Array Toolkit: http://kona.ee.pitt.edu/steve/Recent%20Publications/IWDDC_2012_clutter-final-111108.pdf
