The third transmitter branch transmits a third FMCW signal having a third set of chirps having a third phase setting such that phase values of consecutive chirps differ by a third phase difference. The first phase difference, the second phase difference, and the third phase difference are different phase differences. The first phase difference, the second phase difference, and the third phase difference are asymmetrically distributed relative to each other.Type: ApplicationFiled: July 27, 2022Publication date: November 17, 2022Applicant: Infineon Technologies AGInventors: Sang Ho NAM, Mohit Berry, Byung Kwon PARK

Patent number: 11428796Abstract: A radar system and a method for detecting a target using the radar system. The radar system includes a waveform generator, a plurality of phase shifters, at least one mixer, an analog-to-digital converter, a fast Fourier transform (FFT) processor, and a processor. The waveform generator generates a frequency-modulated continuous wave (FMCW) signal including a set of chirps repeated for a predetermined number of times. The phase shifters shift a phase of each chirp on a transmit branch. The phases transmitted via first and second transmit branches are shifted in accordance with first and second sets of regularly spaced phases, respectively. The first and second sets of regularly spaced phases have first and second phase differences, respectively, that are different from each other. The FFT processor performs FFT processing and the processor determines an angle of direction of the target based on range Doppler map bins.Type: GrantFiled: September 9, 2019Date of Patent: August 30, 2022Assignee: Infineon Technologies AGInventors: Sang Ho Nam, Mohit Berry, Byung Kwon Park

Publication number: 20130067544Abstract: The present invention relates to a system for authentication management of a sensor node having a subscription processing function, and a method for operating the system. Upon receiving information about a sensor node allocated with an IP address, the system supports the access of only authorized user equipment to a corresponding sensor node, which blocking any direct access of unauthorized user equipment to the sensor node, thereby strengthening the security of the sensor node. According to the present invention, a relay server receives subscription information from user equipment. The relay server checks permission validity of corresponding user equipment. If the user equipment has a valid permission, the relay server transmits the subscription information to a sensor node, and transmits subscription acceptance information to the user equipment. Then the sensor node transmits the collected and stored information to the user equipment having a valid permission.Type: ApplicationFiled: May 24, 2011Publication date: March 14, 2013Applicant: Dong-A University Research Foundation for Industry-Acacemy CooperationInventors: Gwang Hoon Kwark, Tae Hoon Kim, Byung Kwon Park, Hyung Rim Choi
