Brain Stroke Detection Based on Microwave Imaging
마이크로파 이미징 기반 뇌졸중 진단

Brain stroke, referred to as a local neurological deficit suddenly caused by abnormal blood flow to brain tissue, is the third leading cause of death after heart disease and cancer. Additionally, because of its very short golden hour, initial treatment and access to diagnostic devices are critical. The main equipment for diagnosing brain stroke are CT and MRI, but it is difficult to carry out continuous tests and the equipment are not portable. CT is detrimental to patients because it uses ionizing radiation, leading to the demand for new devic...

This paper presents the design, manufacture, and performance test results of a highly integrated tile-type transmit (Tx)-phased array antenna for Ku-band satellite communication, which comprises an RF/ANT board and four multi-layer boards. The electrical performance test of the antenna demonstrated a gain and beamwidth of 24 dBi and 12° at the center of the operating frequency in the Ku-band, respectively. Furthermore, the beam squint performance was less than 3° when the steering angles were 0° and 40° in the phi and theta directions, re...

Measurement Method Based on Vehicle Component Installation Position for Radiated Immunity Test of Vehicle Components
차량 부품의 장착 위치를 고려한 부품 내성 시험 방법

Dong-Kyun Kim, Yong Bae Park 김동균, 조춘식

J. Korean Inst. Electromagn. Eng. Sci. 2020;31(2):113-126.
https://doi.org/10.5515/KJKIEES.2020.31.2.113

Test set-up conditions and reference levels are different in the component radiation immunity standard ISO 11452-2 (2004) and vehicle radiation immunity standard ISO 11451-2 (2015); hence, different results may be obtained for the same components. Therefore, even if the evaluation of the radiation immunity of the vehicle is satisfactory, the evaluation of the radiation immunity of the vehicle component may be unsatisfactory. In this study, it is assumed that the chassis of the automobile is a metal plate, and the correlation between the compone...

Effects of Varying the Length of Locally Grounded Cable on Radiated Emission as Per CISPR 25
CISPR 25 규격에서 근지점 접지길이 변화에 의한 복사방출 영향

Hyun-Gwi Hong, Eun-Ha Kim, Jae-Hyun Lee 홍현귀, 김은하, 이재현

https://doi.org/10.5515/KJKIEES.2020.31.2.127

In this study, the ambiguity of the locally grounded wire length defined in the automotive EMI standard CISPR 25 is experimentally investigated. In-vehicle wire grounding conditions are divided into remotely grounded and locally grounded conditions based on the wire length of the battery negative terminal. In the locally grounded condition, the wire length of the battery negative terminal is specified as less than 200 mm; hence, different grounded wire lengths can be used when a tester performs measurements according to the specified locally gr...

Analysis of Shielding Effectiveness for Concrete Material with Crack Using ELND-FDTD Method
ELND-FDTD 기법을 이용한 콘크리트의 균열에 의한 전자기 차폐 효과 분석

Ilyoung Oh 오일영

J. Korean Inst. Electromagn. Eng. Sci. 2020;31(2):136-142.
https://doi.org/10.5515/KJKIEES.2020.31.2.136

The electromagnetic characteristics of concrete using the extremely low numerical dispersion finite-difference time-domain (ELND-FDTD) method have been analyzed. To analyze the electromagnetic properties of concrete accurately, we calculated the weighting factor and scaling factor in the ELND-FDTD according to the frequency, relative permittivity, and conductivity of the concrete. The effects of cracking (width and relative position with perfect electric conductor (PEC) cracking) on shielding effectiveness were analyzed in the overlapping struc...

https://doi.org/10.5515/KJKIEES.2020.31.2.143

A short-range radar sensor was proposed and developed for remote vital signal detection using GHz-band continuous wave (CW) signals. The proposed radar sensor system transmits and receives narrow-band CW signals for monitoring variations in respiration and heartbeat rates at a distance of less than 1 m. Based on the path loss calculation using a human layer model, each radar module, operating at 915 MHz and 2.45 GHz, is implemented with miniaturized antennas, passive components, and a low-noise amplifier integrated circuit. Signal processing al...

Some airborne radars provide the raid assessment mode, which enables the operator to separate closely spaced airborne targets, allowing the operator confirm the number of planes in a dense squadron. This paper presents a design of waveform operation, target extraction, and signal processing method for implementation of the raid assessment mode based on an AESA (active electronically scanned array) radar. The function and performance using our proposed method were confirmed through simulations and a flight test in which the raid assessment mode ...

Algorithm for Estimating the Target Range and Velocity in Sea Clutter
해상 클러터 환경에서의 표적 거리, 속도 추정 알고리즘

Jin-Bae Suh, Joo-Hwan Chun, Ji-Hyun Jung, Jin-Uk Kim 서진배, 전주환, 정지현, 김진욱

https://doi.org/10.5515/KJKIEES.2020.31.2.165

In this paper, we propose a method for suppressing sea clutter and estimating the range and velocity of a slow target with a low SCR(Signal to Clutter power Ratio) using the difference in the velocities and correlation characteristics of the target and sea clutter. Sea clutter is suppressed using the eigenvector corresponding to the smallest eigenvalue of a sample covariance matrix for temporal correlation of sea clutter in the absence of a target in the range-Doppler map. In addition, the velocities of the target and clutter are obtained using...

https://doi.org/10.5515/KJKIEES.2020.31.2.173

Leakage signals, inevitably generated during near-field measurement of a digital radar, affect the measured data samples. Although each leakage signal occurs at a very low level, the signals accumulate and have a significant effect when the measured near-field converts into a far-field beam pattern. In this study, we verified a method that effectively eliminates the leakage signals through back projection from the near-field data. In the simulation, the difference between the characteristics of the noise and leakage signal was examined, and the...

https://doi.org/10.5515/KJKIEES.2020.31.2.188

Herein, we describe the receiving (Rx) near-field measurement of digital active phased array antennas applicable to multifunction radars. Because of the structural differences with analog active phased array antennas, it is difficult to apply the conventional Rx near-field test configuration. Therefore, we have proposed a configuration of a near-field test suitable for digital active phased arrays. In the simulation, the results are presented for the beam pattern distorted by the leakage signal generated in the near field test and the beam patt...

https://doi.org/10.5515/KJKIEES.2020.31.2.200

In this paper, a beam scheduling method for analyzing shipborne multifunction radars using priority queues is presented. The proposed method uses priority queues that use the beam’s emission time as a priority. The priority queues for each of precision tracking, normal tracking, and search consider the significance of the task in performing efficient beam scheduling. We adopted a simulation environment similar to an actual maritime combat situation using a Markov chain. The efficiency of the proposed method is verified via comparison with oth...
