Specifying SNR level of signal returned from Phased Array System Toolbox's function sensorsig

Hi everyone

I need to have an estimation of the SNR level of the signals returned from function sensorsig of Phased Array System Toolbox. The only parameter related to noise i can give to the function is the 'ncov' parameter which is the power level in watts if i understand correctly. Is there a relationship between the power level and SNR? How can i get signals at the sensors with specific SNR? I need to run experiments with different levels of SNR and i haven't figured out how to do that yet.

Thank you in advance

You can specify the signal power if you specify the SCOV input as a scalar. See the reference page at

The SNR can be considered as SCOV/NCOV.
