摘要： A respective electromagnetic parameter and spatial disposition of an unknown number of signal sources in a surveillance space simultaneously bombarded by multiple signals are determined by receiving multiple signals at each of a plurality of widebeam, wideband antennas equally spaced apart in a linear array. Respective antenna signals are simultaneously sampled to generate a two-dimensional array of values. A two-dimensional Fourier transform is computed whose peaks satisfy one or more predetermined criteria, each peak being indicative of a signal source in the surveillance space, whereby the location of the peak in the Fourier transform Fjk indicates the frequency and the azimuth of the respective signal source and the amplitude of the peak indicates the amplitude of the signal source. When implemented using two mutually perpendicular arrays of receiving antennas, an additional Fourier transform of the two-dimensional Fourier transform generates, for each identified emitter, independent azimuth and elevation angles.

摘要： An incoming radio wave is received by array antenna elements which constitute an array antenna, and the correlation between the received data of some array antenna elements is calculated to form a correlation matrix which is not affected by the additive noise at each antenna element. Then a noise subspace is obtained from the correlation matrix by a simple linear operation based on the partition of an array response matrix and is used to estimate the direction of signal (i.e., radio wave) impinging on the array antenna. Because the evaluation of all correlations between the array data received by array antenna elements is not needed, and the eigendecomposition process is avoided, the computational load of the proposed direction estimation technique is reduced, and the noise insensitivity is improved.

摘要： Signals distorted by multipath propagation are reconstructed. In a first step, the incidence direction of the wavefronts, that is to say of the respective d dominant signal components, is estimated and the signal components are reconstructed. The wavefronts are separated as a result of the first step. A second step reconstructs the signals distorted by multipath propagation with the aid of the wavefronts, separated by spatial direction, and therefore with the aid of the reconstructed signal components, through combination of the signal components, by assigning the determined d dominant signal components to the l associated signal sources and, expediently, determining delay times and weighting factors with a view to optimal combination of the signal components in order to reconstruct the signals. The method may be applied either to one-dimensional or two-dimensional evaluation of the incidence direction of the wavefronts, and is suitable, in particular, for mobile-radio or wireless communication systems, high-resolution radar image processing systems and sonar systems.

摘要： The extraction of phase information for radio frequency (RF) direction of rival is attained by pre-detect sensing and quantization of differential phase of a RF wave impinging on two or more antenna apertures, based on sensing and encoding differential phase without the use of conventional detection, and quantizing phase at or near the leading edge of a pulse signal. This is accomplished by detection of an intermediate frequency (IF) carrier, and encoding leading-edge phase (for each channel) in terms of near-phase-difference between two reference-oscillator readings containing the differential phase information--encoded as differential reference-oscillator phase. Precision angle-of-arrival is then derived from the measured differential reference-oscillator phase.

摘要： A method and a system for locating ground equipment transmitting signals to a geostationary satellite, the method and the system being based on identifying the arrival directions of such signals within the coverage zone of the satellite. In the method, the arrival directions of the signals are identified by using a beam-forming active-module array antenna system on board the satellite, the system being controlled to define simultaneous beams in the radiation pattern of the antenna, the beams being superposed on one another with small offsets, the superposed beams corresponding to a limited analysis zone being illuminated within the coverage zone of the satellite, the system further being associated with a digital processing program which identifies the arrival directions of the signals which are received in the analysis zone.

摘要： A method of estimating the directions of radiating sources (56, 58, 60) with respect to an array (46) of a number of antenna elements (48), each of which elements has a separate gain/phase control (50). With nominal gain and phase selected a first estimte of the radiating sources directions (.theta.) is accompished by application of the MUSIC algorithm (2). The algorithm is iteratively applied to a microprocessor (54) using updated gain and phase values. Iteration is terminated at that iteration which produces the maximum difference values of the smallest eigenvalue pair of Q.sub.(i).

摘要： A new signal processing method solves the problem of fitting multiple lines in a two-dimensional image. The Subspace-Based Line Detection (SLIDE) algorithm formulates the multi-line fitting problem in a special parameter estimation framework such that a signal structure similar to the sensor array processing signal representation is obtained. Any spectral estimation method can then be exploited to obtain estimates of the line parameters. In particular, subspace-based algorithms of sensor array processing (e.g., the ESPRIT technique) can be used to produce closed-form and high resolution estimates for line parameters. The signal representation employed in this formulation can be generalized to handle both problems of line fitting (in which a set of binary-valued discrete pixels is given) and of straight edge detection (in which one starts with a grey-scale image).

摘要： An improved signal processing system and technique for preprocessing auxiry data signals by sequential decorrelation, particularly for use in systems employing adaptive cancaller loops. Each of a plurality of signal channels sample the environment of a plurality of signal sources and provide inputs to a configuration of adaptive canceller loops. The loops are connected such that an adaptive loop decorrelates the signal from two signal channels to form a preprocessed signal, and each of the remaining adaptive loops are sequentially connected such that each auxiliary channel signal is decorrelated from the preprocessed signal of the previous adaptive loop until all signal channels have been utilized. In a side-lobe canceller system each of the preprocessed outputs is used to form an auxiliary sample input to a main channel canceller loop to cancel interference in the receiving system. By using the preprocessed signals as the auxiliary input, a receiving system can significantly increase interference cancellation and reduce the number of iterations required.

摘要： The invention described herein relates generally to the field of signal processing for signal reception and parameter estimation. The invention has many applications such as frequency estimation and filtering, and array data processing, etc. For convenience, only applications of this invention to sensor array processing are described herein. The array processing problem addressed is that of signal parameter and waveform estimation utilizing data collected by an array of sensors. Unique to this invention is that the sensor array geometry and individual sensor characteristics need not be known. Also, the invention provides substantial advantages in computations and storage over prior methods. However, the sensors must occur in pairs such that the paired elements are identical except for a displacement which is the same for all pairs. These element pairs define two subarrays which are identical except for a fixed known displacement. The signals must also have a particular structure which in direction-of-arrival estimation applications manifests itself in the requirement that the wavefronts impinging on the sensor array be planar. Once the number of signals and their parameters are estimated, the array configurations can be determined and the signals individually extracted. The invention is applicable in the context of array data processing to a number of areas including cellular mobile communications, space antennas, sonobuoys, towed arrays of acoustic sensors, and structural analysis.
