G01S 15/06

US Classification:

367 99, 367 87

Abstract:

A system and method are presented for determining the detection and location of persons and objects using ultrasonic acoustic sensors. The system allows detection of stationary and moving persons and other objects, through atmospheric conditions, to a distance of at least 300 feet. The invention further provides for enhanced signal processing through the use of arrays of transmitters and receivers, where one or more transmitter arrays may be oriented substantially perpendicularly to one or more receiver arrays, allowing high directionality and good rejection of reverberations, background noise, clutter and objects not of interest.

US Classification:

Abstract:

The present invention is directed to a global positioning system (GPS) having improved signal-to-noise ratio for reducing the required signal level for which GPS may be implemented in electronic devices or cell phones. The acquisition function of the GPS receiver is improved by inserting new signal processing for broadband noise reduction that allows subsequent improved estimation of critical time shift and frequency shift parameters needed for GPS acquisition at lower received signal levels. The decoding of the navigation bits from the satellite transmissions is improved to provide ephemeris data needed for computing navigation solutions at lower received signal levels, by examining the output of the same new signal processing for broadband noise reduction for spikes in the power of the output time series that correspond to navigation bit flips.

International Classification:

US Classification:

Abstract:

Active sonar apparatus, especially adapted for detecting submarine targets under ice, includes means for providing first and second pulsed, underwater acoustic signals respectfully having a high frequency, f. sub. H, and a low frequency, f. sub. L. The high frequency, f. sub. H, is selected for causing the signal to be reflected at the submerged, water-ice interface and and the low frequency, f. sub. L, selected for enabling the signal to be propagated through the ice with no significant reflection at the water-ice interface while then causing the signal to be reflected at the above-water, air-ice interface. Included are means for separately receiving and processing the reflected signals from the first and second acoustic signals and for detecting possible target reflections (which may include ice reflections) as a function of range and angle cells. Further included are signal comparing means for comparing range and angle cells of the two reflected signals, a probable target detection being established when possible target detections for both reflected signals are indicated in corresponding cells. The high and low frequency signals may be separately generated or may be provided as interference signals by a parametric transponder.

Abstract:

An adaptive recursive filter is disclosed which, in a preferred embodiment, comprises first and second adaptive transversal filters selectively coupled together to minimize the mean square error of the output data of the recursive filter based upon observations of input data to the recursive filter. Each transversal filter includes a tapped delay line with a variable weight on each tap. The output data of the recursive filter is developed by combining the outputs of the first and second transversal filters. The input data is applied to the first transversal filter, while the output data is applied to the second transversal filter. The output data is also combined with a reference signal to provide an error signal. A function of that error signal is utilized to update the weights of all of the taps in both transversal filters in order to cause the weights to automatically adapt themselves to minimize the mean square error of the output data of the recursive filter.

Abstract:

This invention relates to a technique and system (34) for clustering a set of data points (18) in a data field. Clustering is performed by a set of rules which make no assumptions about the data fields. That is, the number of clusters, the distance between clusters, etc. , need not be specified in advance. The invention calculates a distance R that is a function of the distances between each pair of points (18) in a data field. Operating on a chosen point, a parameter is calculated for each neighboring point within distance R from the chosen point. This parameter is proportional to the distance of the neighboring point to the chosen point. The chosen point P is then connected to a neighboring point on the basis of this parameter. All points, in any order are operating on as the new chosen point, so that the additional points may be linked to new chosen points in a similar manner. In this way, a tree-structure (22, 24) of connected points will form the desired clustering.

US Classification:

Abstract:

An active adaptive noise canceller that inserts delays into the weight update logic of an adaptive filter to keep the filter stable. The noise and residual noise are sensed and the respective sensor signals are digitized at a given sample rate for processing in the adaptive filter. To eliminate the need for high sample rates while maintaining flexibility in the frequency regions over which the adaptive filter is stable, the delay introduced into the weight update logic is a non-integer multiple of the sample period. The non-integer sample delay is obtained by a sample interpolation and decimation procedure.

Abstract:

An apparatus for destroying a buried object includes a targeting system including a sensor operable to detect the presence and location of an object which is at least partially buried in the ground, a gun system including a gun operable to fire a projectile into the ground, and a control system that aims the gun responsive to the presence and location of the buried object as determined by the targeting system. The sensor also desirably detects the presence and location of the projectile fired by the gun system, and the gun pointer is responsive to the location of the projectile. The sensor thus detects the presence of the buried object, the control system aims the gun at the buried object, and the gun fires the projectile. The sensor detects the relative positions of the buried object and the projectile as it passes near the buried object, the control system corrects the aim of the gun in the event that the prior shot misses, and the gun fires another projectile with a corrected aim.

Abstract:

A broadband adaptive Doppler estimator and canceller is described for adaptively removing a moving source of near field primary interference that is masking a weaker target. The estimator and canceller employs a distributed field of sensors, through which is moving the source of interference. The estimator and canceller takes the form of a canceller system, wherein the measured reference waveform is a Doppler shifted version of the interference. The estimator and canceller employ interpolating and decimating of the reference waveform to remove Doppler effects over a broadband. The interpolation is performed by oversampling (zero padding) and low pass filtering, and the decimation is a sample rate reduction. The adaption is performed in the decimation to minimize mean square error in the canceller output.
