Abstract: Techniques and apparatuses are described that enable low-power radar. The described techniques enable a radar system to reduce overall power consumption, thereby facilitating incorporation and utilization of the radar system within power-limited devices. Power consumption is reduced through customization of the transmission or processing of radar signals within the radar system. During transmission, different duty cycles, transmit powers, or framing structures can be utilized to collect appropriate data based on detected activity in an external environment. During processing, different hardware or different radar pipelines can be utilized to appropriately analyze the radar data. Instead of disabling the radar system, the described techniques enable the radar system to continuously monitor a dynamic environment and maintain responsiveness while conserving power.

Abstract: A controller for a communication and ranging apparatus wherein the apparatus is configured to transmit both a data signal and a ranging signal, wherein the controller is configured to: determine a scheduled transmission event of the data signal; determine a scheduled transmission event of the ranging signal; determine if the scheduled transmission events will occur within a predetermined time window of each other; if it is determined that the scheduled transmission events will occur within a predetermined time window of each other, then determine a priority signal and a secondary signal, wherein: the priority signal is one of the data signal and the ranging signal; and the secondary signal is the other of the data signal and the ranging signal; and provide signaling configured to prevent the scheduled transmission event of the secondary signal from being transmitted such that only the scheduled transmission event of the priority signal is transmitted.

Abstract: A system and method is disclosed where an operating state may be determined by selecting one or more transmitting nodes for transmitting one or more radio-frequency (RF) signals. One or more receiving nodes may receive the one or more RF signals that may include one or more channel state data. The operating state may be determined based on one or more features extracted from the one or more channel state data. Another system and method is disclosed where a range compensation value may be determined by transmitting a radio-frequency (RF) signal from at least one transmitting node. The one or more receiving nodes may receive the RF signal and a channel state data may be estimated using the signal. The range compensation value may be determined using the channel state data and a position value indicating a location of the at least one transmitting node.

Abstract: A radar system includes a transmitter, a receiver and a processor. The receiver receives radio signal that includes the transmitted radio signal reflected from targets in the environment. The received radio signal is provided to the processor. The processor samples the received radio signal during a plurality of time intervals to produce a sampled stream. The different time intervals of the plurality of time intervals will contain different signal levels of radio signals reflected from the targets. The processor also selects a particular time interval of the plurality of time intervals that is free of samples of radio signals reflected off of the targets that are closer than a first threshold distance from an equipped vehicle. The transmitter and/or the receiver is adjusted such that samples of radio signals reflected off of targets that are farther than the first threshold distance are detected.

Abstract: A radar level gauge comprising transceiver circuitry configured to obtain a tank signal including a peak representing a surface echo, and at least one peak caused by a ghost echo in a neighborhood of the surface echo. The gauge further includes a tank signal filter receiving the tank signal as input and providing an echo threshold profile, the threshold profile having at least one local maximum substantially coinciding with one of the peaks in the tank signal, and processing circuitry configured to use the echo threshold profile to disregard peaks in the tank signal which are associated with ghost reflections.The filtering of the tank signal thus provides an adaptive threshold, which is aligned with the peak(s) in the tank signal. By using this threshold in the surface echo identification, at least some ghost echoes occurring in the tank signal may be disregarded.

Abstract: A millimeter wave radar includes an antenna unit including a plurality of antennas that receive millimeter waves, each of the antennas having a prescribed reception range from which the millimeter waves are incident on the antenna; and a signal processing unit that detects, on the basis of a difference between outputs of the plurality of antennas that have received millimeter waves, a moving object moving across the reception ranges of the plurality of antennas.

Abstract: The concepts, systems and methods described herein are directed towards frequency jump burst-pulse-Doppler (FJB-PD) waveforms and processing to provide wideband, high range resolution (HRR) radar profiling capability in a clutter dense environment. The method includes transmitting a FJB-PD waveform comprising a plurality of frequency steps over a predetermined time period with each frequency step having a plurality of pulses. The method further includes receiving one or more FJB-PD pulse returns corresponding to the FJB-PD waveform and identifying one or more target detections in the one or more FJB-PD pulse returns. A set of range swaths may be extracted for each of the one or more target detections and a wideband spectrum may be generated for each of the sets of range swaths using FJB coherent integration. A clutter suppressed HRR profile may be generated for each of the target detections based on the respective wideband spectrum.
