摘要： System and techniques for progressive radar assisted facial recognition are described herein. An image may be obtained from a camera of the security device. A facial target in the image may be identified. The facial target may include a non-empty set of positive facial indicators and also be missing a non-empty set of facial indicators used for identification. In response to identifying the facial target, a power level of a millimeter wave radar may be increased at least until a threshold number of members of the set of facial indicators are observed. Then, the members of the set of facial indicators that are observed may be combined with the set of positive indicators of the face to create a composite image.

摘要： Methods, systems, apparatuses, and computer program products are provided for detecting objects, including humans, using a mobile communications device. A communication space is scanned with a beam-shaped signal transmitted by a phased antenna array of the mobile communications device. Information is discerned from one or more attenuated signals received from the communication space based on the beam-shaped signal. The information is analyzed to determine an object in the communication space. Whether the object is likely at least a portion of a human is determined. A communication signal transmitted by the phased antenna array is modified in response to determining that the object is likely at least a portion of a human, and that the at least a portion of the human has a predetermined spatial relationship with the phased antenna array.

摘要： A radar device including an ADC that performs slide sampling on frequency difference signals outputted from a mixer, and classifies sampling data about the frequency difference signals according to range bins based on a distance resolution corresponding to a pulse width set by a controller, and a speed discrimination unit that separates the sampling data about each range bin after being classified by the ADC according to relative speeds of objects. A distance and speed measurement unit calculates the distance to and the relative speed of an object which has reflected a transmission pulse by using the sampling data after being separated according to relative speeds by the speed discrimination unit.

摘要： A method of detecting weather on an aircraft uses a weather radar system. The method adapts the weather radar system in accordance with a time-of-year parameter, a time-of-day parameter, and/or a location parameter to remove ground clutter reflectivity. The method includes determining the particular parameter and automatically adjusting the weather radar system to display the weather in response to the parameter. The system can be implemented in hardware and/or software and can advantageously predict and identify weather and/or weather hazards more precisely.

摘要： A method and a device for adaptively controlling power in a radar device having a radar transmitter and a radar receiver are provided, in particular for applications in vehicles. The radar signals are emitted, and radar signals reflected off of target objects are received and checked for irregularities. The transmitting power of the radar transmitter is reduced when irregularities occur which are attributable to interference caused by neighboring radar transmitters.

摘要： A system that has a chirp generator for emitting signals and an amplitude modulator for shaping the signals emitted by the chirp generator. The signals are shaped using a calibration ramp. The system further includes a Radio Frequency (RF) power amplifier for amplifying the signals shaped by the amplitude modulator, an RF power detector for measuring power levels of the signals amplified by the RF power amplifier, and a pre-distortion coefficient generator for adjusting the measured power levels using power detector calibration coefficients that correspond to the RF power detector.
