There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract. This talk will discuss time-frequency analysis methods and applications for FM signals using both single-sensor and multi-sensor systems. We first review the interplayed role of the spatial dimension and time-frequency representation for improved time-frequency signature characterization, source discrimination, and signal enhancement. We then introduce recent advances of nonstationary signal analysis and array processing in the following two areas: (a) Nonparametric instantaneous frequency estimation of multi-component signals with closely separated time-varying frequency signatures, and (b) Sparse reconstruction of time-frequency signatures and instantaneous frequency estimation for FM signals with random missing time entries. These methods are supported by application examples including DOA estimation, target localization, and interference mitigation.
