Extreme Bandwidth Radio Frequency Spectrum Analyzer with Direction Finding

A novel radio frequency sensor technology is presented for continuous monitoring of the radio frequency spectrum with large instantaneous bandwidth that can perform spectral analysis and direction finding simultaneously. The photonic receiver technology relies on a spatial spectral (S2) holographic crystal recording device that is an extreme bandwidth analyzer and correlator (EBAC). The S2 EBAC...

A Software-defined Radio Approach for Direction Finding

The increasing demand for wide bandwidth wireless communication in the context of a finite available frequency spectrum has led to an acute need for spectrum-efficient technologies. One solution is the Cognitive Radio approach, a device aware of the environment and able to modify its own parameters accordingly in order to optimize the performance. An important capability that leads to a higher ...

Gps Direction Finding

GNSS receivers provide position information in a convenient way. However, additional orientation information cannot be fulfilled directly by a single antenna receiver up to now. This paper describes an approach for determination of orientation using a single GNSS receiver based only on its own static observations. As estimable base quantity, satellite positions are used as a reference in the mo...

Decoupled direction finding: detection

Antenna arrays are likely to be an important feature of future mobile communication systems. With an antenna array, mobile users can be separated by a spatial filtering procedure allowing several users on the same carrier frequency. The uplink part (mobile to base) not only can, but is better solved without using any spatial knowledge in terms of direction of arrival (DOA). However, DOA estimat...

Generalised clarke model for mobile-radio reception

Clarke’s classical model of mobile radio reception assumes isotropic rich scattering around the mobile receiver antenna. The assumption of isotropic scattering is valid only in limited circumstances. In this contribution we develop a generalized Clarke model, which is applicable to mobile radio reception in general scattering environments. We give expressions for the autocorrelation and power s...
