Costas and sonar sequences were respectively introduced in [2] and [10] to deal with the following problem: "An object ismoving towards (or away) from an observer, who wants to know effectively the distance to the object and its velocity." The solution to the problem makes use of the Doppler effect, which states the following: when a signal bounces off a moving target its frequency changes in direct proportion to the velocity of the object relative to the observer. In other words, if the observer sends out a signal towards a moving target, the change between the frequency of the outgoingand that of the returning signal will allow him to determine the velocity of the target, and the time it took to make the round trip will allow him to determine the distance.
