This report documents the effort under contract W900KK-09-C-0016. The contract comprised four phases spanning 15 April 2009 to 1 December 2012. The relationship between the effort associated with each phase and the contents of this report are as follows: Phase 1 was devoted exclusively to the channel sounding experiments with the UH-1H helicopter. The experimental setup, procedure, and results for the channel sounding experiments at Cairns Army Airfield and Patuxent River are described in Chapter 2. Good, usable data at upper L-band was captured during the Cairns Army Airfield experiments. Phase 2 was devoted to the channel sounding experiments with the C-12 aircraft. Channel sounding experiments were performed at both upper L-band and C-band at Edwards AFB and Pt. Mugu NAWC. The results of these experiments are described in Chapter 2. Good, usable data from both L-band and C-band was captured during the Edwards AFB experiments, and this data was used to form a comparison of multipath propagation at L-band and C-band. Phase 2 also started work on multipath modeling and mitigation. The multipath models, in the form of power delay profiles, are detailed in Chapter 2 for each of the environments where usable data was captured. Multipath mitigation using multiple antennas was also explored. The application of these techniques to the channel sounding data captured in Phases 1 and 2 is summarized in Chapter 3. Phase 3 was dedicated to a study comparing L/S-band systems to C-band systems in the context of aeronautical telemetry. The results of this study are detailed in Chapter 4. Phase 4 comprised a variety of tasks. First, the channel sounding data collected in Phases 1 and 2 were processed and posted on a web page (see http://telemetry.ece.byu.edu/m4a3.php) in a documented, downloadable format for use by all the telemetry community. Second, the behavior of CONSCAN, Monopulse, and E-scan tracking in missile telemetry applications was explored, with an emphasis on the relationship between the performance at S-band and the performance at C-band. These results are detailed in Chapter 6. Third, an in-depth study of C-band missile telemetry was conducted. The findings are summarized in Chapter 5. Finally, the behavior of single-channel and multi-channel equalization for the channels captured in Phases 1 and 2 were explored. These results form part of Chapter 3. The papers and presentations corresponding to this effort are listed in Chapter 7.
