Another great effort resulting in a great potential product!

R. A. Wood Associates designed and built a Direction Finding (DF) Antenna Assembly for one of our customers. The Assembly was designed, built, tested, and delivered in less than 6 months. The requirement was to develop an antenna assembly that could be used as a front end in front of a pair of COTS (Commercial Off the Shelf) receiver boards. The DF Antenna Assembly provided the capability to supply Direction Finding (DF) for incoming signals or emitters. The DF Antenna Assembly included:

• Capability to provide amplitude and phase DF between antenna pairs
• 360 degree angular coverage
• Low cost universal design (can be used with many different receivers)
• Low noise figure RF front end (~3.5-4.0 dB)
• Calibration injection to calibrate receiver amplitude and phase
• Wide frequency coverage (500 MHz to 3 GHz)
• High dynamic range
• Digital Compass for DF Antenna Assembly pointing information
• RF switches controlled by an Ethernet interface
