摘要： A radar sensor scans an environment to identify, for each target, a candidate target volume. A camera, fixed to the radar sensor, captures an image of the environment, and runs an image recognition algorithm to identify target boundaries for each target. The radar sensor determines a refined target volume, by selecting and keeping a first part of the candidate target volume located inside the target boundaries and removing a second part of the candidate target volume located outside the target boundaries.

摘要： Disclosed herein are systems and methods for action potential-based object detection. Received signals corresponding to multiple chirps can be grouped based on temporal or spatial attributes. Within these groups, successful detections can be identified when at least one signal satisfies an action potential threshold. The presence of a valid object is confirmed when the number of groups with successful detections satisfies a predetermined detection threshold.

摘要： A radar device includes a radar front end configured to send radar signals and to receive reflected radar signals, processing circuitry configured to provide digital radar data based on the received reflected radar signals, and a digital filter configured to process the digital radar data to obtain information about objects which reflected the radar signals. The device further comprises machine learning logic with a policy network configured to set the parameters of the digital filter based on the digital radar data, and a reward value generating network including a plurality of heads, each head configured to provide a respective expected reward value for a setting of parameters by the policy network. The radar device is further configured to detect that a scene captured by the radar device is not reliably processable based on a distribution of the expected reward values generated by the plurality of heads.

摘要： In an example, the present invention provides a method for processing rf backscattered signals. The method includes generating a plurality of rf signals numbered from 1 to N, where N is an integer greater than 1, from, respectively, a plurality of rf sources numbered from 1 to N. In an example, each of the rf sources is an antenna. In an example, the method includes transferring the plurality of rf signals to a predetermined region of space. The method includes receiving a stream of back scattered signals derived from each of the rf signals numbered from 1 to N from the predetermined space, each stream of back scattered signals being one of a plurality of backscattered signals numbered 1 to N corresponding, respectively, to the plurality of rf sources numbered from 1 to N. The method includes processing each stream of the backscattered signals, using a digital signal processor, at a predetermined time to normalize the stream of backscattered signals to form a normalized signal corresponding to the stream of the backscattered signals and outputting a plurality of normalized signals numbered from 1 to N corresponding, respectively, to the plurality of back scattered signals, numbered from 1 to N.

摘要： One-dimensional data obtained by performing a Fourier transform on a digitally converted frequency modulated continuous wave (FMCW) radar signal at every pulse repetition interval is input to a recurrent neural network (RNN) to find the probability of the existence of a target in each range index. The range indices, i.e., bit frequencies are selected based on the probability. In order to reduce the size of the RNN, windowing may be applied. In addition, a speed-index-specific coefficient value may be calculated by accumulating and performing a Fourier transform on the selected bit frequencies in which the target exists over a plurality of pulse repetition intervals. Thus, it is possible to calculate the speed of the target.

摘要： A system may include a display and a processor. The processor may be configured to: break down two-dimensional weather radar reflectivity data into cells, each cell of the cells having a maximum rainfall rate location and a geometric area; prioritize the cells based at least on each cell's proximity to the aircraft, each cell's intensity, each cell's growth rate, each cell's storm top altitude relative to the aircraft altitude, and/or a threat convective level of the cell to select a highest priority cell; and output, to the display, a highest priority azimuth slice vertical radar image of the two-dimensional weather radar reflectivity data as graphical data, the highest priority azimuth slice vertical radar image corresponding to an azimuth slice of the two-dimensional weather radar reflectivity data for the highest priority cell. The display may be configured to display the highest priority azimuth slice vertical radar image.

摘要： A mm-wave system includes transmission of a millimeter wave (mm-wave) signal by a plurality of transmitters to multiple objects, and receiving of return—mm-wave signals from the multiple objects by a plurality of receivers. A processor is configured to perform an algorithm to derive complex-valued samples and angle measurements from each receiver to identify one object from another object. The processor further extracts signal waveforms that correspond to each object and process the extracted signal waveforms to estimate breathing rate and heart rate of the identified object.

摘要： A suspicious person alarm notification system includes one camera including artificial intelligence and a radar and capturing an image of a person, and a server communicating with the camera. The camera receives a signal presenting in an emission direction of the radar, acquires vital information on the person from the signal, acquires, by using the artificial intelligence, motion information on the person from a captured image, calculate an index indicating suspicious person likelihood of the person based on the vital information and the motion information on the person, and transmit, to the server, person information related to the person in response to determining that the index is equal to or greater than a threshold value. The server outputs an alarm indicating that a suspicious person is detected.
