The Ohio Argus Array

Home Technical Real-Time Displays Show-and-Tell Contact

The Ohio Argus Array detects transient narrowband and broadband radio signals from arbitrary locations in the sky. Ohio Argus detects narrowband radio sources,such as orbiting satellites. Argus doesn't "point" at a satellite like a dish-type antenna would have to. Instead, Ohio Argus detects that a signalis "present" in the data collected from the elements of the array, andthen mathematically figures out the location of the satellite in the sky.

Ohio Argus also detects the sun, and is able to localize it accuratelyin the sky. Other strong celestial sources are just outside Argus's detection limit, however, with the possible exception of Cygnus X andCas A. An expanded Argus and/or more sensitive receivers will be able to detect much fainter celestial radio sources.

But Argus is still useful at detecting local radio emitters. Take aircraft,for example. At certain frequencies, Argus can detect some jets as theyapproach and depart Port Columbus International Airport. The jets areeither broadcasting the signals detected by Argus, or they are reflectingradio waves which are emitted from a transmitter somewhere in the generalarea.

While current plans for the expansion of Argus are on hold - pendingnew volunteers with RF experience ready to take charge - the volunteerswho run the day-to-day operation of the Array can benefit from additionalhelp in other areas. These areas include software development, spare parts assembly and testing, fund raising, site maintenance, and other activitiesnot related to the Argus Array, through NAAPO,the North American Astrophysical Observatory.
