摘要: Radar is playing an increasingly important role in autonomous systems, including autonomous vehicles. However, the cost of radar systems and low output quality (e.g., resolution, accuracy and/or smoothness) are factors limiting the adoption and utility of radar systems. Disclosed are methods and devices to use machine learning models to increase the quality of the output of a radar system.

摘要: A ghost removal method includes steps of detecting, estimating and excluding. In the detecting, a position and a relative speed of a target moving object, and a position of a surrounding stationary object are detected with radio waves. In the estimating, a position and a relative speed of a ghost by the target moving object are estimated based on the detected position and relative speed of the target moving object and the position of the surrounding stationary object. In the excluding, a detected point where the estimated position and the relative speed of the ghost are detected is excluded from a candidate detection point of a moving object which is detected with radio waves.

摘要: A self-calibrating sensor system is provided and includes one or more sensors supportively disposed on or proximate to a wall defining one or more apertures and a processor. Each of the one or more sensors is configured to track individuals proximate to at least one of the one or more apertures. The processor is configured to determine one or more of a location and an orientation of each of the one or more sensors relative to the at least one of the one or more apertures from analyses of the tracking of the individuals.

摘要: The embodiments described herein provide a radar device and method that can provide improved sensitivity. In general, the embodiments described herein provide a saturation detector and reset mechanism coupled to a radar receiver. The saturation detector is configured to detect saturation events in the radar receiver, and the reset mechanism is configured to reset at least one filter unit in the radar receiver in response to detected saturation events. As such, the embodiments can facilitate improved radar sensitivity by reducing the effects of saturation events in the radar receiver.

摘要: Embodiments are provided for a radar device and a method of operating a radar device, the radar device having a transmitter and a receiver, the method including: generating a chirp signal based on a local oscillator (LO) signal, wherein the LO signal is a frequency-modulated continuous-wave (FMCW) signal; secondary modulating the chirp signal to produce an output signal; transmitting the output signal on a transmitting antenna of the radar device; receiving an echo signal on a receiving antenna of the radar device; downmixing an amplified version of the echo signal with the LO signal to produce a low frequency signal; and outputting an error detection signal based on spectral components of the low frequency signal, wherein the spectral components correspond to the secondary modulating.

摘要: Systems and methods are provided for detecting face creep of a longwall mining system. The system includes a detection device mounted in a maingate roadway and coupled to the detection device. The controller determines the position of the beam stage loader-armored face conveyor interface based on a signal from the first indicator device, determines a position of a maingate line based on a signal from a maingate indicator device, and determines a position of a belt conveyor based on a signal from a belt conveyor indicator device. The controller further determines a first distance between the position of the beam stage loader-armored face conveyor interface and a maingate line, and a second distance between the position of the belt conveyor and the maingate line. The controller generates an indication of face creep based on the first distance and the second distance.

摘要: A method for correcting a fluorescence image of an object, for example a biological tissue that can include fluorescent agents. The distance between a fluorescence probe generating the fluorescence image and the object examined is measured. This distance is used to apply a correction function to the fluorescence image. The method may find application in perioperative fluorescence imaging for diagnosis and monitoring of evolution of pathologies, for example of cancers.

摘要: A method of using a directional sensor for the purposes of detecting the presence of a vehicle or an object within a zone of interest on a roadway or in a parking space. The method comprises the following steps: transmitting a microwave transmit pulse of less than 5 feet; radiating the transmitted pulse by a directional antenna system; receiving received pulses by an adjustable receive window; integrating or combining signals from multiple received pulses; amplifying and filtering the integrated receive signal; digitizing the combined signal; comparing the digitized signal to at least one preset or dynamically computed threshold values to determine the presence or absence of an object in the field of view of the sensor; and providing at least one pulse generator with rise and fall times of less than 3 ns each and capable of generating pulses less than 10 ns in duration.
