Field Test Results with the Targeted Search MCSA

Abstract

In April 1985, a 74000 channel prototype of the multi-channel spectrum analyzer (MCSA) that NASA plans to use in a systematic search for extraterrestrial intelligence (SETI) was installed at DSS13, a 26 meter R&D antenna facility at the Goldstone Deep Space Network (DSN) site. Since that time the instrumentation has been used to validate the performance of signal detection algorithms using locally injected signals and the weak carriers from distant spacecraft. It has been used in an unsuccessful attempt to relocate the Pioneer 9 spacecraft, which now has been officially decommissioned. It has also been used to collect large data samples in order to study the statistical behavior Of the noise in that observatory environment. The prototype has provided a limited capability to communicate with the telescope control computer and test schemes for automated operation during the Microwave Observing Project (MOP) Targeted Search mode. This paper describes results from the Goldstone Field Tests and plans to move the prototype equipment to other sites where SETI may be conducted in the future.
