Abstract:

Autocell is a computer-controlled h.f. radio interferometer employing a single twin channel receiver for automatically taking contemporary measurements of the direction of arrival of up to ten transmissions of different frequencies propagated via the ionosphere. The basic hardware and software features of the system are described together with the results of preliminary measurements made with the system during acceptance trials early in 1976. System limitations which might restrict its usefulness as a research tool for the study of ionospheric radio propagation and h.f. transmitter locating techniques are reported. Author
