Abstract

In this paper, a new approach is presented for tone resolution and estimation problems in such applications as pulse Doppler processing and direction finding. The new approach, based on frequency diversity signaling and coherent wide-band high-resolution processing, is shown to significantly outperform those using the conventional signaling and narrow-band high-resolution processing under the equal transmitted-energy constraint with either completely correlated or independent targets. Both analytical analysis and simulations are provided, as well as some insights on issues related to the performance of narrow-band high-resolution processing methods and the effectiveness of “smoothing” techniques.
