International Classification:

H01J 334

US Classification:

250398

Abstract:

A deflecting magnet assembly for scanning an incident beam of charged particles in a scanning electron beam computed tomography scanner. The configuration (including angular orientation and coil end connection geometry) of the coils which comprise the magnet is selected to approximate the field of a pure dipole. In addition, a magnetic shield is used which equalizes the effective radii of the constituent coils and thereby simplifies construction of the assembly.

International Classification:

G01S 7/35
G01S 13/42
G01S 13/92
G01S 13/34

Abstract:

In accordance with described examples, a method determines if a velocity of an object detected by a radar is greater than a maximum velocity by receiving on a plurality of receivers at least one frame of chirps transmitted by at least two transmitters and reflected off of the object. A velocity induced phase shift (φ) in a virtual array vector S of signals received by each receiver corresponding to a sequence of chirps (frame) transmitted by each transmitter is estimated. Phases of each element of virtual array vector S are corrected using φto generate a corrected virtual array vector S. A first Fourier transform is performed on the corrected virtual array vector Sto generate a corrected virtual array spectrum to detect a signature that indicates that the object has an absolute velocity greater than a maximum velocity.

International Classification:

G01S 7/35
G01S 13/34
G01S 13/931

Abstract:

An apparatus, including processing unit (PU) cores and computer readable storage devices storing machine instructions for determining a distance between a target object and a radar sensor circuit. The PU cores receive a beat signal generated by the radar sensor circuit and compensate for a phase difference between the received beat signal and a reconstruction of the received beat signal to obtain a phase compensated beat signal. The phase compensated beat signal is then filtered to remove spurious reflections by demodulating the phase compensated beat signal using an estimated frequency of the phase compensated beat signal. The PU cores then apply a low pass filter to the demodulated phase compensated beat signal, resulting in a modified beat signal. The PU cores then determine the distance between the target object and the radar sensor circuit using the modified beat signal.

International Classification:

G01S 7/02
G01S 13/58

Abstract:

In an example, a method is implemented in a radar system. The method may include transmitting, via transmission channels, a frame of chirps, the chirps transmitted having a programmed frequency offset that is a function of a transmission channel of the transmission channels that is transmitting the frame of chirps, receiving, via a receive channel, a frame of reflected chirps, the reflected chirps comprising the chirps reflected by an object within a field of view of the radar system, and determining a Doppler domain representation of the frame of reflected chirps having a Doppler domain spectrum that includes multiple spectrum bands, the object represented in at least a portion of the spectrum bands based on the reflected chirps, wherein the programmed frequency is configured to cause the Doppler domain spectrum to include a number of spectrum bands greater than the number of transmission channels.
