IMPROVED MEASUREMENT TECHNIQUES FOR SPECTRAL POWER OUTPUT DATA

The objective of the study program is to pursue a continued research and development effort with the goal of increasing the capability of automated interference measurements in the frequency range of 100 kc to 40 gc. Investigation is being directed toward the design, on paper, of a single receiver having the combined capabilities of a spectrum signature, field surveillance, field intensity and other types of broadband receivers. During the course of this study pro gram, major emphasis will be placed on investigation of techniques in two specific areas: (1) voltage-tunable, solid-state receivers; and (2) automated techniques for the presentation. Where necessary, various techniques will be breadboarded for comparison or feasibility purposes. The program output will be a final report describing the relative merits of the techniques investigated. The design of a receiver utilizing the techniques which best fulfill the program goals will also be presented on paper. Field tests were run on the existing AN/GRR-9, a voltage-swept field surveillance receiver. The results of these field tests were applied as inputs to the present receiver study program.
