I want to create a dict(121*256).

121 means DOA from -60~60 degree.

And 256 is fast time sample points.

I guess the waveform of each row may be "sinc wave".

And after I create the dict, how can I check the DOA of each row is really what I expected?

Does the function steervec and mvdrweights meet my needing?

Thanks!

Looks like you are trying to simulate the received signal? Yes it can be done, but you haven't provide any info about the array itself. You may want to take a look at the following example describing the workflow about simulating a signal and then retrieve the DOA from it.
