Write a MATLAB code showing a simple airborne radar. Assume stationary. There is a target with a certain cross section (say about 25m²) at a lower elevation at a certain angle, assume stationery as well. That target reflects some pulses back to the radar. There is also some pulses from the environment under the target. Let's say some terrain. In can be as simple as you would like for modeling purposes. The model should be a typical PSD sketch of radar returns. Of course your model will differ depending on the terrain and if you decide to depict the noise for EXTRA CREDIT.
