A chinese destroyer is pinging an american sub. Now the distance between the 2 is so great that the destroyer has no usefull echo. On the other hand the american sub uses the reflected ping to "illuminate" chinese subs that are nearby as well as the chinese destroyer. So it finds them on sonar.

It is mathematically possible, assuming a ridiculously insensitive Chinese sonar unit versus a ridiculously sensitive American sonar unit combined with the right geometry and some lucky ducting effects that will reduce propagation loss.
Unfortunately, since that's basically the essence of Clancy's entire assumption in pretty much every one of his books, especially SSN (everyone that's not American is deaf, while Americans are all seeing), it can work - in Clancyverse.
