Wideband vertically polarized omnidirectional antennas for direction finding (DF) system
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014In this work, wideband vertically polarized omnidirectional antenna candidates for a direction finding (DF) system are presented, which operate over frequency spectrum between 100 MHz to 1300 MHz (frequency ratio: 13:1). Two antenna solutions based on Spirograph monopole and bow-tie monopole were designed, developed and experimentally verified. To ease

A low cost HF direction finding antenna array simulator for verification of HF-DF receivers
2014 IEEE AUTOTEST, 2014Field tests of High Frequency (HF)-Direction Finding (DF) receiver often require deployment of the antennas and transmission of a test signal. It is a difficult task for most of the HF-DF receiver depending on number of the antennas and the distance between them.

A novel array configuration for improving the direction-finding (DF) accuracy of an interferometer DF system is presented. The interferometer DF system that uses a single array configuration provides a high DF accuracy over a wide frequency range. However, the DF accuracy in the low-frequency range for this array configuration is lower than that of the

DSSS detection and direction finding methods for a DSP-based small aperture DF system
2005This dissertation discusses an investigation into methods for detection and direction finding of direct-sequence spread-spectrum signals (DSSS), appropriate for a particular DSP-based direction finding platform. Relevant details on DSSS and radio direction finding are presented. These are used as the theorectical basis for the developemtn of a software-
