|
 | In this performing period, we have focused on radar imaging with the synchronized RF link. Specifically, after synchronizing, we fix the slave node, and move the master node smoothly, collecting raw correlator output continuously. From the starting and stopping time of the master motion, and the known distance, we estimate the relative master and slave positions in 2D (Figure 1). These positions, and the correlator outputs are combined in a ... |

| In this reporting period, we are continuing to collect indoor data and processing the scans for improving the indoor range accuracy. Since the transceivers are very tightly synchronized, the transmission phase and time and the phase use for down conversion are well-controlled and repeatable as we perform the experiments. As a result, we observe a clear correlation between the range error and the correlation amplitude. In Figure 1, we show ... |

|
| The objective of this study has been to develop a data-adaptive matched field procedure to detect coherently and incoherently across networks of stations at local and regional distances. The detector extends the single-phase matched field processing approach to detection using the entire waveform. The procedure is based upon a narrowband signal representation that exposes the invariant spatial and temporal correlation structure of network signals from repeating sources. The matched field ... |

|
| The ability to rapidly and accurately detect signals is essential in the modern warfare environment. However, the ever increasing use of the spectrum places great demand on current technology and, requires significant technological developments to overcome current limitations. Also, the nearly ubiquitous miniaturization of military systems requires a concomitant reduction in the size of radiating apertures. Therefore, in order to deal with these challenges, advanced artificial materials are used, namely, ... |

| Resource utilization for behavioral healthcare at Fort Carson has been increasing since the year 2000. Traditionally, a static algorithm based upon population and provider ratio has been used to forecast resource utilization. A more effective forecasting methodology would use a scientifically derived predictive equation based upon personnel correlates. Establishing personnel correlates with behavioral health resource utilization is the focus of this graduate management project. A literature review identified 11 personnel ... |

|
| This report represents the culmination of a study focusing on more extensive characterizations of a robust autoregressive locally optimum (ARLO) detector for spread spectrum signals operating in a variety of noise environments. The signal is modeled as corrupted by both Gaussian and Non- Gaussian noise as representative of many interference environments. The normal linear correlator is sub-optimum, as is a fixed non-linearity. The ARLO algorithm, in contrast, uses an adaptive ... |

|
| The maximum-likelihood sense optimum detector for the detection of randomly fluctuating multiple highlight objects in Gaussian reverberation and noise is an Estimator-Correlator (EC). If a large time-bandwidth product signal is used, a conventional matched-filter detector can spread scattered energy into multiple detector bins, resulting in lower output in each bin than if all the energy had been concentrated in just one. The wideband, or Wavelet Transform ... |

| Space-time adaptive processing schemes effecting both equalization and interference cancellation for mobile narrowband digital communications under time-varying multipath conditions were developed. Interference cancellation was effected through the use of an "extended correlator" exploiting past symbol decisions to highly localize in time the contribution due to the desired signal. This facilitated a "dead" time zone during which the spatial correlation matrix of the interference could be estimated ... |

| A GPS Code Tracking Receiver Design for Multipath Mitigation Using Maximum Likelihood Estimation |

| Authors:
Fred P. Baier; AIR FORCE INST OF TECH WRIGHT-PATTERSONAFB OH
|
| The NAVSTAR Global Positioning System (GPS) is currently used in many applications requiring precise positioning data. Improving the precise positioning information requires the removal of errors that perturb the received signals. The errors introduced by multiple propagation channels, termed multipath, are not easily removed. These channels are caused by reflective surfaces near the receiver. As such, multipath is uncorrelated between receivers and, thus, cannot be removed through differencing techniques. This ... |

| The NILE UHF fixed frequency waveform employs an RS (48,30) error control code with 8-bit characters. The code is used both to correct errors and to identify when the decoder has failed to produce a correct codeword. When this code is used on a memoryless binary symmetric channel, the probability of codeword error is 10(exp-5) when the channel bit error probability is 0.5%, and the probability of undetected decoder error ... |
