摘要： An unknown location for a transmitter/receiver is determined using a calibration process. An area is established with reference receivers at known locations and a mobile transmitter provides a location signal. An alternative embodiment uses reference transmitters and a mobile receiver. For calibration, the transmitter is placed at multiple measured locations and signal measurements are taken to generate a calibration map. Multiple signal measurements may be taken at each receiver, and multiple receivers may be used. In one embodiment, signal measurements include a near-field phase. In operation, one or more location signals are measured at one or more receivers. The measured signals are compared with the calibration maps to generate a set of comparison maps which are combined to generate a likelihood map. A likely region and most likely location are determined from the likelihood map and may be displayed relative to a map of the environment.

摘要： A directive electrically small antenna (DESA) process and method employs multipole synthesis to implement directive electrically small multipole antennas with ultra-wideband (UWB) stable antenna patterns. Although lossy, embodiments have adequate efficiency to work as receive antennas in the high ambient noise environment of the HF band and below. Employing a process dubbed “antenna regeneration,” energy may be circulated within an antenna by means other than resonance. This enables multiple decade UWB response without the efficiency penalties inherent to traditional resistively-loaded antenna systems. Regenerative antennas can simultaneously achieve the performance of high Q resonant antennas and the bandwidth of resistively loaded antennas.

摘要： A multiple phase state near-field electromagnetic location and communication system includes a multiple phase state near-field transmitter, and a near-field locator receiver. The near-field transmitter is capable of operation in at least two states and each of these at least two states generates a state characteristic difference detected at the near-field locator receiver. The state characteristic difference may be employed for location determination, communication or both. The present invention is particularly well-suited for use in conjunction with a near-field electromagnetic ranging system. In further embodiments, a multiple phase state near-field electromagnetic location and communication process includes the steps of determining a transmission state for a near-field quadrature transmitter, transmitting a near-field transmission corresponding to said transmission state, receiving a near-field transmission corresponding to said transmission state, and determining a difference between at least two properties of said near-field transmission where the difference is characteristic of and corresponding to the transmission state.
