ELECTRONICS PROGRAM. RADIO FREQUENCY INTERFERENCE AT ORBITAL ALTITUDES.

Abstract

The program plan, Radio Frequency Interference at Orbital Altitudes, was initiated because of the lack of information and effort in this field that is essential for future reliable communications in space. Higher and higher transmitting powers and more crowded frequency bands are responsible for ever increasing RFI problems that demand solution. The broad objectives of this program are to study the RFI problem and to investigate the design of monitoring instruments suitable for making in-space measurements of the electromagnetic environment. Toward this objective laboratory development of a compact, lightweight receiving system in the 200 to 1000 Mc band has been initiated. The receiving system is to consist of an antenna array, a bank of interdigital bandpass filters, and sixteen crystal-video receivers. The results of tests on breadboard and prototype circuits have demonstrated the feasibility of this instrumentation concept. Hardware development is progressing on schedule. It is anticipated that the first RFI monitor will be placed in orbit in the spring of 1964. (Author)
