摘要： Systems and methods for using magnetic field readings to refine device location estimates are provided. As an example, a plurality of magnetic field readings can be collected by a device as it travels along a path. A positioning system (e.g., GPS) or other sensors can be used to provide a coarse location for the device at each reading. A contribution to each of the magnetic field readings by the Earth's magnetic field can be removed to obtain a plurality of residual readings and a plurality of regions of interest along the path can be identified based at least in part on the residual readings. The regions of interest can be compared to each other to identify a plurality of correspondences between magnetic field readings or residual readings and the plurality of correspondences can be used to refine the location estimates.

摘要： A method surpresses clutter in a space-time adaptive processing system. The method achieves low-complexity computation via two steps. First, the method utilizes an improved fast approximated power iteration method to compress the data into a much smaller subspace. To further reduce the computational complexity, a progressive singular value decomposition (SVD) approach is employed to update the inverse of the covariance matrix of the compressed data. As a result, the proposed low-complexity STAP procedure can achieve near-optimal performance with order-of-magnitude computational complexity reduction as compared to the conventional STAP procedure.

摘要： A method and system are provided for measuring water current. An acoustically-modulated beam of radiation is transmitted to a target location on the surface of a body of water. As the beam transits the water, acoustic radiation propagates away from the beam towards the surface and experiences a Doppler shift in frequency relative to the acoustic frequency used for modulation. The Doppler shift is caused by current in the water through which the acoustic radiation transits. The Doppler-shifted frequency is measured as an indication of water current.

摘要： A transmitting/receiving antenna radiates a sweep frequency signal as an interrogation signal to an answer device. The answer device includes a plurality of resonators which are connected in parallel and have different resonance frequencies and answer antenna means connected in parallel with these resonators and transmits resonance answer signals including ringing answer signals corresponding to the resonators, in response to the interrogation signal. A phase adjusting means is provided which receives at the inputs the sweep frequency signal and the resonance answer signal and adjusts the phases of these signals to have the phase difference therebetween 0.degree. or 180.degree.. The output of the phase adjusting means is applied to a detector where the ringing answer signals are detected to form binary answer signals corresponding to the ringing answer signals, respectively. An object with the answer device fixed thereat is identified from these binary answer signals.
