How to add noise to RangeAngleResponse in phased.array toolbox?

Hi there,

I'm going to create some 2D(range-angle) images of FMCW radar, and it seems like the object RangeAngleResponse meets my needs.

But the documents of it doesn't mention anything about how to add noise (like Gaussian) to it.

1.Is there any property port provided that I can add noise?

2.Why I can not find the function phased.RangeAngleResponse in my Matlab?

The version of my sw is 2017b, and I just installed 2017b_update 9.

I always get the error: Undefined variable "phased" or class "phased.RangeAngleResponse".

3.

NumAngleSamples — Number of samples in angle span

positive integer greater than two

Number of samples in angle span used to calculate range-angle response, specified as a positive integer greater than two.

It means that I can not create a 2D image that only one object in it?

Thanks!

Here are my answers:

1. The noise should be added in the raw signal. Normally the noise is not added on the range-Doppler response itself.
2. You need Phased Array System Toolbox. You can use ver command to find out if you have access to it.
3. NumAngleSamples determines how many scans we do across azimuth region. It is one of the dimensions of resulting 2D matrix. It has nothing to do with how many objects are in the scene.
