Question

What does the author explain about the SAR sonar

tracking system?
SAR finds objects underwater by bouncing
electronic sound waves off of them.
We had used Jean-Louis' brand-new SAR system, a sonar
tracking instrument that looked like a red torpedo. But
we had not found anything. We had covered a lot of
ground, but the ocean currents had been very strong.
They had often pushed us off course, wasting precious
time. Already we were behind schedule. Sonar is used to
find underwater objects by bouncing electronic sound
waves off them.

Red torpedoes were used to track the objects on
the ocean floor.
The strong ocean currents wasted time, keeping
the scientists behind schedule
