Abstract

Many months of active participation in the satellite and missile observation program have resulted in a number of new and improved concepts which have been put to practical use in the establishment of the U.S. Army Signal Research and Development Laboratory's Astro-Observation Center, Fort Monmounth, N. J. This paper will describe the capabilities of the Research and Development station and several of the instrumentation techniques in use, including the use of phase-locked audio-frequency tracking filters, and high-speed digital readout equipment for precision Doppler measurements. The extreme flexibility of frequency coverage of the station has been of exceptional value in the rapid acquisition of signals transmitted from foreign satellites and space probes.
