What is Barker code used for?

Barker codes are used for pulse compression of radar signals. There are Barker codes of lengths 2, 3, 4, 5, 7, 11, and 13, and it is conjectured that no longer Barker codes exist.

Is Barker code used for spread spectrum?

Here, 11-bit Barker code is used to spread the spectrum; however, other spreading codes having any bit-size may also be used instead of 11-bit Barker code.
