    摘要: A receiver exploits unique higher order statistics of temporally dependent waveforms to classify, characterize, identify (fingerprint) and intercept a waveform within the field of view of the receiver. The method uses 4th-order non zero lag auto cumulants of the received waveform and 4th-order non zero lag auto cumulants of known waveforms to classify and characterize the signal. The receiver includes a multi-element array and does not need a priori knowledge of the transmitted signal source obtain a fingerprint.

    摘要: A transmitted signal's higher order statistics of temporally dependent waveforms are exploited to geolocate low power signals. The geolocation is independent of the characteristics or encoded data of the transmitted waveform. The method uses spatial fourth order cumulants or spatial second order moments in a Blind Source Separation and generalized eigenvalue decomposition to determine unique matrix pencil eigenvalues and eigenvectors. The eigenvectors provide are orthogonal to the steering vector of the transmitted signal save one, which represents the steering vector. This property is used to determine Steering vectors, AoA or geolocation. The receiver includes a multi-element array and does not need a priori knowledge of the transmitted signal source to geolocate the target transmitter. The methods and apparatus for geolocation does not require typical demodulation.

    摘要: Embodiments of a system and method are disclosed that exploit the unique higher order statistics of temporally dependent waveforms to detect and enumerate signals in a multi-signal and noise environment. The embodiments use spatial 4th-order cumulants or spatial 2nd-order moments in a Blind Source Separation operation and generalized eigenvalue decomposition to determine unique matrix pencil eigenvalues for a set of unknown signals. Sequential detection in the complex plane of the eigenvalues in associated tracks for successive blocks of sensor data serve as the basis of the detection decision. The embodiments may include a multi-element array and do not require a priori knowledge of the signal environment to detect and enumerate the signals.

    摘要: The present invention provides, an apparatus for controllably moving a vehicle's work implement. The work implement includes a first appendage pivotally connected to the vehicle, and a second appendage pivotally connected to the first appendage. The apparatus senses the geometry of the work implement and responsibly producing a plurality of position signal and produces one of a manual control mode signal and an automatic control mode signal. An operator interface produces first and second lever command signals indicative of desired movement of the work implement. The apparatus receives the one control mode signal and the first and second lever control signals and responsively produces linear motion of the end point of the second appendage along first and second work axes if the one control mode signal is equal to the automatic control mode signal.
