Question about radar target classification example in Phased Array System Toolbox

Hello everyone,

I am very interested in the radar target classification example in Phased Array System Toolbox. https://ww2.mathworks.cn/help/phased/examples/radar-target-classification-using-machine-learning.html

And I have some questions about the modeling and simulation.

Q1: Which type of radar is used in simulating? Pluse or CW? I can not find more details except BackscatterRadarTarget.

Q2: How far is the object from the radar? I think that the distance between the object and the radar has effects on the echo signal, but I just can see the cylinder radius and height.

Q3: This example uses SVM method to classify the radar returns. How about CNN, DNN? Would get me some helpful advice?

That is all the questions. Hope for your answer. Thank you.

The simulation used a pulse radar but I think the concept is independent to what type of radar one is using. It just looks at the RCS signature in the echo. Also the target is assumed to be in the far field. The distance does affect the echo, but in the example, the two targets are assumed to be at the same range, therefore, there is no relative power difference due to range between the two.

Given this is a simple classification problem, we didn't try the deep learning algorithms.
