A new design method is proposed that can increase the efficiency of a Fabry-Perot cavity antenna enclosed with metallic side walls, in which high-order modes are formed. A TE031 mode inducing drastic phase and magnitude variations in the electric fields inside the cavity was analyzed. To alleviate the variations, two microstrip patch antennas at which the electric field magnitude is zero were installed. Consequently, when an electric field whose phase is almost constant and magnitude varies gradually inside the cavity is formed, the proposed an...

https://doi.org/10.5515/KJKIEES.2021.32.9.762

This study proposes a capacitor switching scheme that reduces both the energy consumption and area through multiple reference voltages of a capacitive digital to analog converter (CDAC), a component of successive approximation register (SAR) analog to digital converter (ADC). With a 10-bit SAR-ADC, if the reference voltage is used as 3-bit with a 6-bit capacitor array, the energy and area (number of capacitors) are reduced by 99.97 % and 93.75 %, respectively. Furthermore, we propose a switching algorithm that minimizes energy consumption, whic...

In this study, we propose a miniaturized Ka-band transceiver module with a microstrip-to-waveguide transition structure that can be applied to high-capacity wireless radio. We apply a probe-shaped transition structure with the vertical structure of a substrate and waveguide that can mount a filter on top of a transceiver module. Measurement results of the fabricated transition structure revealed an insertion loss of 0.67 dB or less and a return loss of −14.1dB or more in the frequency range of 28～30 GHz. Measurement results of the transceiv...

A Measurement Technique of Phase Noise Using a Digital Oscilloscope and Labview™
디지털 오실로스코프와 Labview™를 이용한 위상잡음 측정방법

Kyung-Whan Yeom, Jin-Seong Roh 염경환, 노진성

J. Korean Inst. Electromagn. Eng. Sci. 2021;32(9):782-794.
https://doi.org/10.5515/KJKIEES.2021.32.9.782

In this paper, we propose a novel phase noise measurement method using Keysight's 4-channel 10-bit digital oscilloscope MSO804A and National Instruments' Labview™. Precise phase noise measurement equipment is generally expensive and not universal, whereas digital oscilloscopes are universal. Therefore, via the method proposed in this paper, it is possible to perform precise phase noise measurements inexpensively and easily. To evaluate the proposed phase noise measurement method, the phase noises of three types of source under test (SUT), Key...

Design of Wideband Digital Frequency Discriminators with Multiple Channels of Low-Speed ADCs
다중 저속 ADC를 이용한 광대역 DFD 구조 설계

This paper proposes an alternative method for measuring the frequency of a short-time signal in a wideband frequency range. A frequency measuring architecture comprising multiple sub-Nyquist sampling channels and a frequency estimator is proposed. The simulation results show that the proposed method has better frequency accuracy, though it uses lower sampling rates than typical DFDs for wideband input frequency range.

Spotlight SAR Processing of Stripmap Data using a Range Doppler Algorithm in Airborne SAR
항공기 탑재 SAR에서 거리 도플러 알고리듬을 이용한 Stripmap 데이터의 Spotlight SAR 처리 기법

Jeonghun Hwang, Hyung-Suk Kim, Sang-Ho Yoon 황정훈, 김형석, 윤상호

J. Korean Inst. Electromagn. Eng. Sci. 2021;32(9):806-815.
https://doi.org/10.5515/KJKIEES.2021.32.9.806

This study presents the considerations needed to create a spotlight SAR image of wide beam stripmap data using a range doppler algorithm (RDA). We propose applying preprocessing methods to the conventional autofocus method, which is necessary for airborne SAR to spotlight images captured by the RDA. Finally, it is proven that a wide swath stripmap SAR image can be generated through the azimuth matching of spotlight image blocks. The wide beam stripmap raw data acquired by the flight test was used to validate the proposed processing method.

A Novel Clustering Method for Multi-Target Localization Based on Unidentified RSS/AOA Measurements in Wireless Sensor Networks
무선 센서 네트워크에서 다중 표적 위치추정을 위한 미식별 RSS/AOA 측정치 기반의 군집화 기법

Se-Young Kang, Tae-Hyun Kim, Won-Zoo Chung 강세영, 김태현, 정원주

J. Korean Inst. Electromagn. Eng. Sci. 2021;32(9):816-825.
https://doi.org/10.5515/KJKIEES.2021.32.9.816

In this study, we present a novel clustering method for multi-target localization in wireless sensor networks (WSNs) when measurements are not identified with their original targets. Without any knowledge on the origin of measurements, existing hybrid target localization algorithms that utilize both the received signal strength (RSS) and angle of arrival (AOA) measurements are unable to estimate the location of multiple targets. We propose multiple clustering methods based on the k-means and expectation maximization (EM) algorithms to identify ...

https://doi.org/10.5515/KJKIEES.2021.32.9.826

Multi-temporal synthetic aperture radar (SAR) images, which are obtained to monitor the ground area at different observation times, are utilized in change detection (CD) to identify changing objects in the observed area. However, even with co-registration processing, it is impossible to achieve perfectly matching multi-temporal SAR images. In this study, we compared the change detection performance of four different CD techniques under various co-registration conditions. We analyzed the change detection performance of these techniques in terms ...

https://doi.org/10.5515/KJKIEES.2021.32.9.836

In this study, the design of a low-cost frequency-modulated continuous wave (FMCW) radar system at C-band using commercial off-the-shelf (COTS) components is presented. The proposed radar system consists of low-cost surface-mounting devices and monolithic ICs on a multi-layer FR4 PCB for system integrity. The Tx/Rx antennas (Cantennas) were fabricated with commercial cans based on waveguide dominant mode analysis. The proposed radar system is connected to the Arduino UNO platform, which transfers the received analog backscattered RF signal to M...

A Study on the Acceleration of a Speckle Reduction Algorithm using GPUs
GPU를 이용한 고속 스페클 제거 알고리즘에 관한 연구

Geon Lee, Myung-Jun Lee, Nam-Hoon Jeong, Jae-Ho Choi, Kyung-Tae Kim 이건, 이명준, 정남훈, 최재호, 김경태

J. Korean Inst. Electromagn. Eng. Sci. 2021;32(9):845-855.
https://doi.org/10.5515/KJKIEES.2021.32.9.845

When a synthetic aperture radar (SAR) image is created, if there are some scatterers in the resolution cell, the reflected signals from the scatterers interfere with each other, causing irregular changes in the intensity of pixels in the image called speckles. Speckles increase the false alarm rate and decrease the pixel detection rate. Therefore, speckle reduction filters have been developed to reduce the influence of speckles. However, filters that reduce large amounts of speckles have a long processing time; therefore, they are costly to use...
