Justification

SwRI is an independent, not-for-profit, applied engineering and
development organization devoted to technology development and transfer.
Business is conducted with industry and government (U.S. and other
friendly nations) on a worldwide basis. Approximately 50% of the Institute’s
business is for the U.S Government. SwRI has been involved in direction
finding (DF) research and development since 1951. Direction finders are
receive-only devices utilizing the energy of passing electromagnetic waves
to determine their direction of arrival. Direction finding systems can then be
used to determine the direction to an emitter. The original DF research and
development has expanded to include, among other things, the interception
and recognition of a large number of standard and special signals. SwRI
must transmit signals to test the systems and do this in real-world
environment. The systems are designed to process planar wavefronts in the
far-field of the transmit source. The transmitter must thus be located at a
significant distance from the receiver and, therefore, real-world conditions
cannot be simulated by testing in an anechoic chamber of any realistic size.
Typical testing of systems at SwRI is very intermittent. SwRI typically
transmits for only a few seconds to one or two minutes for a given test
frequency and is always at a low power level (< 10 watts input to antenna).
Extremely rarely there might be a need to transmit for several hours,
especially in the HF frequency range when HF skywaves reflected off the
ionsphere change significantly over time and day/night transition. Once the
test is complete there can be a period of several months before some other
system is ready for testing. Because the systems are used to acquire and DF
on any frequency that occurs in its contractually specified operating
frequency range, a large number of test frequencies is required. Indeed, the
very frequencies that are in common use are the ones most often of interest
to our customers.
