Grammar

From the use of echolocation, or sonar as it also called

From the use of echolocation, or sonar, as it also called, microbat can tell a great deal about a mosquito or any other potential meal.
[Source: Reading for Results Ninth Edition by Laraine Flemming]
I think "as it also called" modifies "sonar," but that the comma after "sonar" disconnects the modified with the modifier.
So, I'd like to know why the comma is used after sonar."
Thank you in advance for your help.

" There are commas before and after 'as it is also called'; they function as parentheses. Note that I have added a word that was omitted.
