Abstract :
An optimum signal in the form of a linearly-increased frequency-hopped uniform pulse train is derived and analyzed. This signal possesses some good wideband ambiguity properties that are useful for many practical applications. In this paper, the proposed signal is specifically used as the source input in the context of target localization in which time delay and Doppler stretch estimation based on the wideband ambiguity function are required. A significant improvement in terms of estimation accuracy is obtained
