Systems and methods for monitoring life signs in a subject. A radar unit comprising generates raw data and a processor unit receives raw data and identifies oscillating signals in a series of arrays of complex values representing radiation reflected from each voxel of a target region during a given time segment. A phase value is determined for each voxel in each frame and a waveform representing phase changes over time for each voxel is generated. Voxels indicating an oscillating signal are selected and life sign parameters are extracted.

Systems and methods for remotely tracking life signs with a millimeter-wave radar

A printed circuit board mounted radar system for monitoring a target region, including an array of transmitting antennas mounted to a printed circuit board, an array of receiving antennas mounted to the printed circuit board, a wave deflection mechanism mounted to the printed circuit board configured such that waves transmitted perpendicularly to the board by the array of transmitting antennas are incident upon the wave deflection mechanism and are directed radially away from the board, and waves reflected from objects within the target region radially towards the wave deflection mechanism are directed towards the receiving antennas in a direction perpendicular to the board.

Systems and methods for providing wide beam radar arrays

Systems and methods for sensing the surroundings of vehicles via vehicle mounted radar sensors. A directional transmitter array transmits radiation into the region surrounding the vehicle and a receiver array receives the radiation reflected back. Controllers may use self-velocity calculation modules, wall detection modules, dynamic range enhancement modules, double reflection detection modules and the like to harvest useful information such as the vehicles relative speed and the identification of hazards in its surroundings.

Systems and methods for sensing the surroundings of a vehicle

There are provided methods and systems configured to perform calibration of antenna array systems, for example during production, avoiding the use of external setups or external measurements. The method comprising: (i) measuring the delay of a dedicated calibration transmission line for each SUT, for example during production, using internal built-in system capabilities; (ii) comparing the measured delay to a known delay of an identical transmission line of a reference system; (iii) computing, based on this comparison, compensation values with respect to the reference system of delay (or phase), for all transmission lines of the SUT; (iv) calibrating the SUT using the computed compensation values for all transmission lines of the SUT.

Systems, devices and methods of transmission line calibration for antenna array systems

Antenna array systems and methods for simulating QPSK beam forming having binary phase shifter associated with each transmitting antenna configured to apply a phase shift of 180 degrees to a transmitted signal, and a controller configured to send instructions to the binary phase shifters. The receiving antennas are connected to a post processor comprising a memory operable to save received signals; and a processing unit operable to apply a 90 degree phase shift to selected received signals stored in the memory, and further operable to sum received signals stored in the memory. Optimized antenna array configurations are disclosed.

Systems and methods for shaping beams produced by antenna arrays

Systems and methods for providing wide field-of-view radar arrays. Quadrature phase-shift keying (QPSK) beam forming reduces side lobes by applying a phase shift to transmitted signals to selected transmitting antennas. Super-hemispherical radar coverage at high gain in both broadside and end-fire directions is provided by beam directing elements mounted to a printed circuit board.
