I read across places that cross-correlation of two signal (a radar sending a signal and receiving it back) one can detect the location (distance) of a target from a point and that cross-correlation can be used for comparing signals.
I solved a question to find cross-correlation of two finite length sequences where:
The cross-correlation sequence came as:
The answer was also correct as per my verification.
But I am not able to understand how using the above cross-correlation sequence value I can state it to be used for -
a)location of a target? b)comparing signals x and y?
