Direction Finding Using Compressive One-Bit Measurements
IEEE Access, 2018 In this paper, we propose a novel direction-of-arrival (DOA) estimation scheme, which is named the compressive one-bit measurement scheme. In the proposed scheme, the one-bit quantization technique is used to reduce the system cost in terms of the analog-

Biologically inspired direction‐finding for short baseline
IET Radar, Sonar & Navigation, 2021 The optimal implementation for a biologically inspired coupling structure to overcome the limitation of short baseline direction‐finding is determined. This approach is inspired by the Ormia ochracea, a parasitoid insect living in North America.

Real time wideband direction finding
2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015 In this paper, the developed FFT based interferometric direction finding of wideband radar threats for electronic support (ES) and electronic intelligence (ELINT) is presented. Using this method, target radar signal is separated from other radar signals using FFT. Phases of extracted radar signals for two or more channels are calculated.
