SABRE is a new sensitive Naval Electronic Support Measures system covering frequency bands in the range 0.5 to 40 GHz. SABRE uses both conventional multi-port amplitude comparison techniques and multiple phase interferometers for the extraction of the accurate direction of arrival (DOA) of a signal using a common set of eight antenna/receiver channels per band. The same set of antenna/receiver channels also provide a pseudo-omnidirectional coverage for the measurement of frequency, pulse width, amplitude and time of arrival. SABRE provides all parameter measurements on a wide-open, pulse by pulse basis for processing by a highly integrated Signal Analysis Processor (SAP). The SAP uses purpose designed VLSI devices to handle the very high mean and peak data rate complex signal environments of today. This paper describes the overall architecture of the SABRE system, the approach to a common phase and amplitude antenna/receiver design, the components used in the phase measurement receiver, and the algorithms used in the DOA extraction process.
