  • Patent number: 11047970
    Abstract: A multi-mode radar system, radar signal processing methods and configuration methods, including using predetermined, range/mode-specific pushing windows to perform windowing on range and velocity object data before performing an FFT on the windowed object data matrix to generate a three-dimensional object matrix including range, velocity and angle data. The individual windows have an angular spectral response that corresponds to a combined angular coverage field of view of the transmit and receive antennas for the corresponding mode to minimize the total weighted energy outside the main lobe and to provide increasing spectral leakage outside the combined angular coverage field of view with angular offset from the main lobe to push out much of the spectral leakage into regions where leakage tolerance is high due to the corresponding combined angular coverage field of view of the transmit and receive antennas.

  • Patent number: 11035931
    Abstract: Systems and methods are provided for a computer-implemented method for generating a display of radar returns. A geometry data structure is accessed that identifies characteristics of a region of interest including dimensions and movement of one or more objects in the region of interest. A pulse of a plurality of rays is transmitted from an antenna position into the region of interest and the velocities of returns of the rays are captured at a receiver position after the rays have interacted with the one or more objects. Each ray return is assigned into one of a plurality of bins based on the velocity of that ray. A Fourier transform is performed using the binned data to obtain a system response at discrete time intervals. The system response at the discrete time intervals is transformed into Doppler velocity data, and the Doppler velocity data is stored and displayed on a graphical user interface.

  • Patent number: 11035946
    Abstract: This disclosure provides systems through which a wireless access point (AP) can determine the location of a client device with a high degree of accuracy. The AP uses CIR measurements for a plurality of directional beams used to communicate with the client device to determine a respective amplitude of a Line-of-Sight (LOS) path between the AP and the client device for each beam. The AP identifies a high-LOS-amplitude subset of the beams and, based on predefined radiation patterns associated with the beams included in the high-LOS-amplitude subset, determines a direction of the LOS path between the AP and the client device. The AP also determines a Time-of-Flight (ToF) for radio frames exchanged between the AP and the client device via the plurality of directional beams and uses the ToF to determine a distance between the AP and the client device.

  • Patent number: 11022674
    Abstract: If a vehicle surroundings monitoring apparatus is equipped with four radars disposed at each of the four corners of the body of a vehicle in order to detect an object around the vehicle, the interfere of the radio waves of the radars likely to occur. As a result, the accuracy for detecting an object by the radars will deteriorate. Specifically, if two of detection areas are adjacent to each other of the radars overlaps with each other and the two of the radars transmits radio waves at the same time, the interfere of the radio waves will occur in the overlapping area. In view of this, the four radars are divided into two groups such that the detection areas of two radars within the group aren't adjacent to each other and transmission period of one of the groups and that of the other of the groups are repeated alternately.

  • Patent number: 11018757
    Abstract: Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.
