Abstract:

This report summarizes research supporting communication, tracking and imaging systems. Four specific topics were addressed during this study Active Communication Systems Communications between incoming aircraft and carrier air traffic control are normally by radio and visual landing aids, which are not available during EMCON conditions. Several potential low probability of intercept communication systems were conceptualized and analyzed. Spread Spectrum Tracking The objective of this task was an assessment of various approaches for aircraft tracking based on spread spectrum technology for reducing the probability of intercept. Two specific transmit receive architectures were examined 1 beacon on aircraft and 2 spread spectrum waveform from a rangeDoppler radar on board ship. MMW Imaging Evaluation Millimeter wave imaging system capabilities are progressing rapidly. A survey of current and projected MMW imaging capabilities was conducted, identifying several potential systems. Wind Detection A current interest of the Navy is the remote detection of wind vectors around carriers and other aviation-capable ships. Microwave radar sensing of the flowfield is one possible approach. This study shows that, because of the very low backscatter from atmospheric constituents, very high transmitter power would be required to achieve acceptable signal to noise levels.
