摘要： An ultra wideband system employing a threshold to detect signal quality during acquisition wherein the threshold is adjusted based on signal characteristics such as packet traffic rate, packet loss rate, and packet loss fraction. In one embodiment, the threshold is adjusted by adjusting the gain of a variable gain stage ahead of the threshold. In another embodiment, gain and threshold are adjusted in a coordinated manner wherein gain is adjusted for low signal levels and threshold is adjusted for high signal levels. In one embodiment, packet traffic rate is evaluated over an interval based on maximum packet length, number of monitor packets, and inter-packet delay. In a further embodiment, multiple ramp builders are operated in parallel at multiple code offset values to generate signal statistics to compare with the threshold. Embodiments are disclosed wherein the thresholds are adaptively adjusted based on signal performance characteristics or the multipath environment.

摘要： A system and method are provided that can detect any part of a multipath impulse radio signal. More specifically, the method compares a template pulse train and the multipath impulse radio signal to obtain a comparison result. The system performs a threshold check on the comparison result. If the comparison result passes the threshold check, the system locks onto any part of the multipath impulse radio signal including a direct path part and at least one multipath reflection part. The system may also perform a quick check, a synchronization check, and/or a command check of the multipath impulse radio signal.

摘要： Time is transferred from an ultra wideband (UWB) transmitter to UWB receiver by transmitting a signal structure having an associated timing reference point together with a time value for the timing reference point. The UWB receiver receives the timing signal structure by synchronizing a receiver time base to the signal structure, demodulating the time value information, and using the demodulated time value information to set a receiver clock value. Propagation delay information is used to adjust the receiver clock value by advancing the receiver clock value to account for the propagation delay. In one embodiment, propagation delay is determined from a known distance between the transmitter and receiver. In another embodiment, the transmitter and receiver are part of a two-way link wherein propagation delay is measured by round trip timing measurements.

A second video cable is permanently wired to the remote visual display and has a free end that terminates at a plug. To sight the hand-carried weapon without having to look through the sight, the jack is inserted into the plug, to thereby provide video from the sight to the remote visual display. The user fired the rifle from behind cover by viewing the sight reticles through the remote display.

摘要： A system for evaluating properties of materials by probing the materials using ultra wideband signals wherein the probing may be by transmission or by reflection of radiated ultra wideband signals. Received signals may be evaluated by determining signal characteristics including reflection coefficient, transmission attenuation, multipath decay profile, and signal scattering coefficient. Received signals are evaluated using deconvolution and Fourier processing. Test chamber characteristics and boundary reflections may be removed to yield bulk material properties. The system may be calibrated by employing empirical signal measurements from materials with known properties measured by reference techniques.

Correlation of the multipath response with a model pulse shape may be used to establish pulse position and amplitude. Iteration based on link performance measurements may be used to select or refine pulse properties. A method is disclosed to vary the selection of pulses to improve the spectrum.
