  • Patent number: 11269052
    Abstract: A signal processing method is provided. First, at least one transmitted signal is output to at least one target, and the target reflects at least one reflected signal to receiving antennas, which then generate receiving signals upon receipt of the reflected signal. Next, the transmitted signal and each receiving signal are processed to generate processing signals. The processing signals are arranged in a form of matrix, to generate a channel coefficient matrix having M×N channel coefficient matrix blocks. Next, the channel coefficient matrix is divided into Ndivide×Mdivide secondary channel coefficient matrices, which are then substituted into a snapshot vector matrix equation to generate a snapshot vector matrix for calculating an angle of the target. The signal processing method can establish an optimal secondary channel coefficient matrix arrangement by using a special signal preprocessing manner, to improve the resolution and accuracy of the estimated angle parameter of the target.

  • Patent number: 11262458
    Abstract: Various embodiments of the present technology generally relate to Global Navigation Satellite Systems (GNSS). More specifically, the embodiments of the present technology relate to a smart antenna module resistant to Radio Frequency Interference (RFI) saturation for dual-frequency GNSS receivers. In some embodiments, a dynamically configured antenna module architecture can be for a dual-band (or multi-frequency) GNSS receiver that can adapt to different RFI conditions by performing corresponding working modes. For example, some embodiments of the smart antenna can measure (e.g., using a power detector) the power of an incoming multi-frequency signal to determine when the multifrequency signal is saturated. Then, using control logic the smart antenna can determine which frequency in the multi-frequency signal is usable and isolate (e.g. using radio frequency components) a frequency that is not saturated. A position estimate can then be generated based on the isolated multi-frequency signal.

  • Patent number: 11243306
    Abstract: In a method for estimating a position of a missile, an incident angle of a signal of a radar irradiated to the moving missile is calculated. The incident angle is defined by an angle between a measurement vector indicating a direction from the radar toward the missile and a movement vector indicating a moving direction of the missile. A distance compensation value from a point on a surface of the missile to an origin point of the missile is calculated based on the calculated incident angle. A distance from the radar to the origin point of the missile is calculated based on the calculated distance compensation value and a distance from the radar to the point on the surface of the missile. A position of the missile is estimated based on a position of the radar and the calculated distance from the radar to the origin point of the missile.

  • Patent number: 11231494
    Abstract: A radar system having a vehicle assist function with a field of view greater than 160 degrees is provided. The radar system includes antenna boards and a processing unit. The antenna board includes multiple antennas disposed thereon and transmitting a detection signal to detect an obstacle outside the vehicle, and then receiving a reflected signal, generated by the detection signal reflected by the obstacle. Therefore, the single radar system is enough for the vehicle assist function, and the transmitting and receiving antennas are disposed on the antenna board. The processing unit can directly analyze the reflected signal to determine a distance between the obstacle and the vehicle, and perform different vehicle assist functions having different warning distances, and when the distance between the obstacle and the vehicle is lower than one of the warning distances, the processing unit outputs a warning message to warn a driver.

  • Patent number: 11226411
    Abstract: One or more aspects of this disclosure relate to the usage of an impulse radio ultra-wideband (IR-UWB) radar to reconstruct a cross-sectional image of subject in a noninvasive fashion. This image is reconstructed based on the pre- and post-processing of recorded waveforms that are collected by the IR-UWB radar, after getting reflected-off the subject. Furthermore, a novel process is proposed to approximate the different tissues' dielectric constants and, accordingly, reconstruct a subject' cross-sectional image.
