RF Tag Devices

Description

S*R Long Range RF Tags are passive retroreflectors which reflect radiation back in the direction from which it came. Because of retroreflective gain (the same principle exhibited by road signs and bicycle reflectors) the radar return is quite large for the size of the tag. Typical operating ranges are on the order of 1,000 meters for tags illuminated by a hand-held radar to ranges exceeding 60 miles for tags illuminated by an airborne radar. Tag modulation is matched to the signal processing capabilities of the interrogating radar.

Angle of Arrival Simulation

Description

S*R has developed an Angle of Arrival (AOA) Simulation test employing microprocessor-controlled electromechanical hardware which duplicates the effect of electromagnetic signals impinging on the SUT.
S*R's Angle of Arrival Simulation uses a centroid technique measuring the field from four antennals arranged in a square (quad). This is identical to finding the mechanical C.G.
This approach offers several advantages over flight testing:

There is no risk of accident or signal compromise
Cost per run is much lower that flight test
EM Environment levels can be independently tailored to suit test requirements
Spectra Research's approach uses a panel with 15 antennas and the associated hardware. This approach offers the advantages of simpler equipment, and the ability to simulate different signals.
