The Catadioptric Omni-Directional System was developed by the U.S. Army Armament Research, Development <strong>and</strong><br />
Engineering Center (ARDEC) Acoustic <strong>and</strong> Network Sensors Office, Picatinny Arsenal, New Jersey to demonstrate existing<br />
technologies that could increase situational awareness for the M1A2 Abrams’ crew. The project required a rapid <strong>and</strong> easily<br />
incorporated solution that could attach to the tank without permanent modification <strong>and</strong> at low cost. On 23 February 2005, the<br />
completed system was demonstrated to PM Abrams’ Tank Urban Survivability Kit (TUSK) Program Manager.<br />

The objective of this project was to develop a fiber-optic RF link with high Spur Free Dynamic Range (SFDR). The<br />
approach taken was to utilize coherent AM modulation techniques which would, theoretically, provide a6dBadvantage over<br />
Intensity Modulation/Direct Detection methods, <strong>and</strong> then insert a linearized electro-optic modulator in an attempt to achieve<br />
an SFDR of 130 dB Hz. In the coherent AM portion, locked homodyne detection <strong>and</strong> COTS components were used to achieve<br />
a measured SFDR of \g 120 dB Hz at a 10 GHz operating frequency. The link, which used polarization maintaining<br />
components throughout <strong>and</strong> fusion splices instead of connectors, had none of the instabilities historically associated with<br />
homodyne systems. Efforts were made to raise the SFDR by using a Y-fed linearized directional coupler modulator; extensive<br />
measurements <strong>and</strong> theoretical analyses were made on these devices. The modulators showed the linearization predicted by<br />
theory; a logarithmic slope of 4.6 was demonstrated. Some shortcomings were also observed <strong>and</strong> analyzed that shed light on<br />
the difficulties of achieving wideb<strong>and</strong> operation. The present devices can be designed to operate at specific center frequencies<br />
with maximum performance, but the linearized b<strong>and</strong>width is less than 2 GHz.<br />
