Obtaining excellent performance from a complex electromagnetic device like a correlative interferometric direction finding antenna system is challenging because they:
Although DF algorithms are the responsibility of the customer when integrating a DF antenna array into their system, angle of arrival estimation can be improved greatly when careful DF array characterization and array manifold generation procedures are performed on a special RF test range with:
Cyntony's facility for such testing is the SA National Antenna Test Range (NATR), located at Paardefontein, just north of Pretoria, South Africa; and about 35 miles from our maker of such DF antenna systems: Alaris Antennas. This 30 acre facility is fully equipped with automation and measurement equipment to facilitate accurate and efficient DF calibrations, such as for the DF-A0001 shown on the elevation-over-azimuth positioning system at the VHF/UHF Building of the NATR.
Calibration service can be ordered with the purchase of a DF antenna system such as the DF-A0001, DF-A0029, DF-A0031 and DF-A0095.
This service can also be performed on a previously delivered DF antenna system. Either way, you'll get excellent array manifolds for your direction finding algorithms.
