Progress in the Development of a Direction Finding System Utilizing the 8-Loop Fixed Spaced Loop Antenna: Interim Development Report for Direction Finder Radio, Shipboard Siting and Design, Study and Development
Abstract
The development of a D/F system using the 8-loop antenna (fixed spaced loop) is discussed. New results obtained with the 8-loop antenna and both the twin channel technique and the goniometer method are presented. An improved 8-loop goniometer system has been constructed to provide a laboratory breadboard to solve the basic engineering problems of the system. The receiver requirements for a goniometer scan D/F system are discussed in detail with comparisons of the R-390A, RA.17C and the AN/SRD-7. Other project work reported for the interim period includes phase stability measurements on the R-390A and RA.17C receivers. Detailed analysis of polarization response of spaced loop antennas is reported. Brief discussions of the status of the hybrid transformer and the DFG-4 UHF direction finder are given.
