摘要： Methods, systems, computer-readable media, and apparatuses for determining one or more attributes of at least one target based on eigenspace analysis of radar signals are presented. In some embodiments, a subset of eigenvectors to use for forming a signal or noise subspace is identified based on principal component analysis. In some embodiments, the subset of eigenvectors is identified based on estimating the total number of targets using a discrete Fourier transform (DFT) or other spectral analysis technique. In some embodiments, a DFT is used to identify areas of interest in which to perform eigenspace analysis. In some embodiments, a DFT is used to estimate one attribute of a target, and eigenspace analysis is performed to estimate a different attribute of the target, with the results being combined to generate a multi-dimensional representation of a field of view.

摘要： Disclosed herein are techniques for measuring a reference beam and a corresponding returned beam from a target in a measurement system using a single sensor array. The system is configured such that the location of the reference beam is space apart from the location of the returned beam on the sensor array. A first set of sensor elements on the sensor array corresponding to the reference beam is dynamically activated based on a laser beam scanning control signal. The detection signal from the first set of sensor elements is used to determine a location and/or a pattern of the reference beam, which are then used to estimate a location and/or a pattern of the corresponding returned beam on the same sensor array and dynamically select and activate a second set of sensor elements on the sensor array based on the estimated location and/or pattern of the corresponding returned beam.

The system may further receive, from a second one-dimensional radar array, second information based at least in part on second reflections associated with an elevation plane. Accordingly, the system may detect an object based at least in part on the first information and may determine an elevation associated with the object based at least in part on the second information. Numerous other aspects are described.

The detector is configured to receive a reflected light pulse, where the reflected light pulse is reflected off of an object. The amplifier is coupled to the detector to generate an analog signal in response to the reflected light pulse. The TDC is coupled to the amplifier to generate a first time data and a second time data in response to the analog signal. The integrator is coupled to the amplifier to integrate the analog signal. The ADC is coupled to the integrator to sample an output of the integrator and to generate a digital sample. The processor is configured to process the first time data, the second time data, and digital sample to estimate a total reflected energy of the reflected light pulse.
