Patent number: 11923889Abstract: Various embodiments include methods and systems having detection apparatus operable to cancel or reduce leakage signal originating from a source signal being generated and transmitted from a transmitter. A leakage cancellation signal can be generated digitally, converted to an analog signal, and then subtracted in the analog domain from a received signal to provide a leakage-reduced signal for use in detection and analysis of objects. A digital cancellation signal may be generated by generating a cancellation signal in the frequency domain and converting it to the time domain. Optionally, an estimate of a residual leakage signal can be generated and applied to reduce residual leakage remaining in the leakage-reduced signal. Additional apparatus, systems, and methods can be implemented in a variety of applications.Type: GrantFiled: September 27, 2022Date of Patent: March 5, 2024Assignee: Futurewei Technologies, Inc.Inventors: Ricky Lap Kei Cheung, Luzhou Xu, Lixi Wu, Hsing Kuo Lo, Yuan Su

Publication number: 20210215816Abstract: A radar system transmits pulses towards a target and receives pulses reflected back therefrom. Based on samples (of the received pulses) corresponding to a CPI, a first 2D matrix having a slow-time index and a fast-time index is generated. A slow-time FFT is performed to convert the slow-time index to a Doppler bin index to produce a second 2D matrix having the Doppler bin index and the fast-time index. Thereafter, a 1D interpolation is performed along the Doppler bin index to produce a third 2D matrix having a Velocity bin index and the fast-time index. Thereafter, a fast-time FFT is performed to convert the fast-time index to a Range bin index to produce a fourth 2D matrix having the Velocity bin index and a Range bin index. A distance to and a velocity of a target is determined based on the fourth 2D matrix.Type: ApplicationFiled: March 11, 2021Publication date: July 15, 2021Applicant: Huawei Technologies Co., Ltd.Inventors: Luzhou Xu, Ricky Lap Kei Cheung, Hsing Kuo Lo, Jianghua Ying, Yuan Su
