Abstract: A UWB radar device having two or more first antennas includes a generating and transmitting assembly of a UWB signal having a predetermined number of generating and transmitting circuits of a UWB signal, a receiving assembly for processing the received UWB signal, and a processing and control logic unit. The predetermined number of generating and transmitting circuits is lower than the number of the first antennas. The UWB radar device further includes a first selector connected with at least one of the generating and transmitting circuits of the signal and with at least two of the first antennas so as to convey the received signal to the first antennas. The processing and control logic unit includes a memory unit, in which a delay and sum algorithm executable by the logic unit is stored so as to manage the change of phase of the signals received in the receiving assembly.

Abstract: Method and apparatus for enhance medical imaging and identification with potential image resolution up to 1000 times smaller than diffraction limit, wavelength. Recording of wavefront of good body penetrating Radio Frequency (RF) electromagnetic waves in form of digital hologram allows to recreate 3 dimensional images of objects. Reference signals in set of monopulse antennas with overlapping squinted beams provides enhanced image resolution and allows suppression of scattering medium influence. Transforming of reflected near field signals to frequency-space-time domains allows identification of objects and scattering medium by spectrum signatures. Direct digitizing and digital interface for connection to multi-channel signal processor allows loose distributing of transceiver antenna modules around object or in small space.

Abstract: Examples disclosed herein relate to a radar system and method of angular resolution refinement for use in autonomous vehicles. The method includes transmitting a radio frequency (RF) beam to a surrounding environment with a beamsteering radar system and receiving return RF beams from the surrounding environment. The method also includes generating radar data from the return RF beams and detecting objects from the radar data, and determining a direction of arrival of each of object and determining an angular distance between the objects. The method further includes initiating a guard channel detection based at least on the angular distance and determining gain amplitudes of the return RF beams, and determining a null between the objects from the gain amplitudes and resolving the objects as separate objects based at least on the determined null. The method also includes determining a refined direction of arrival of the objects based at least on the resolved objects.
