Robust Relocatable Physical Security System

Two essential elements of any physical security system are the security sensors themselves and the communications network which interconnects them. Highly sophisticated biometric sensors which provide rapid, accurate personnel identification are currently available from several vendors and it is Nova Engineering's opinion that further development in this area does not represent the best value to the government at this time. Far more significant shortcomings exist in the area of the communications subsystem, particularly for security systems which must be frequently relocated. Wired interconnects are secure and jam resistant but are extremely labor intensive to install; this is impractical for relocatable systems. Wireless links, on the other hand, are very easy to install but existing reasonably priced receivers are easily spoofed or jammed, even unintentionally. Robust anti-jam MIL-spec transceivers, such as SINCGARS and HAVE QUICK are available, but their size, weight power consumption, and cost are all very high. This proposal describes Nova Engineering's innovative approach to mitigating these deficiencies. By combining current state-of-the-art biometric sensors with our unique Sinusoid-Free Spread Spectrum modulation, we are able to provide a low cost, high performance approach to Robust Relocatable Physical Security Systems.
