Radar detects the position and movement of objects by transmitting radio waves. It is often used to detect targets such as air defense interceptors, warships, and fighter jets, owing to its long maximum detection distance compared with optical devices such as cameras and infrared. Radar can measure the distance to an object and the speed and direction of movement of an object. However, owing to the limitations of its resolution, it is difficult to distinguish targets in situations in which multiple targets, such as missiles flying in clusters, ...

https://doi.org/10.5515/KJKIEES.2025.36.5.436

This paper proposes a dual-band amplifier implemented in a 40-nm complementary metal-oxide-semiconductor (CMOS) process that supports both the V-band (64 GHz) and the D-band (144 GHz) frequencies. Without employing additional active components, the input and output matching networks leverage resonant characteristics to enable dual-band operation within a single chip. Measurement results demonstrate that the proposed amplifier achieves a peak gain of 6.2 dB with a 3 dB bandwidth of 12.4 GHz at 64 GHz and a peak gain of 4.93 dB with a 3 dB bandwi...

https://doi.org/10.5515/KJKIEES.2025.36.5.445

Since 2010, the mobile communications market in Korea has operated under an oligopolistic competitive structure dominated by three mobile communications companies. However, since 2020, with the full-scale rollout of 5G services, the competitive landscape has shifted from subscriber-centric competition to competition focused on service quality and content, leading to a more complex evolution of inter-operator competitive relationships. This study analyzed changes in the competitive relationships among the three operators in the domestic mobile c...

https://doi.org/10.5515/KJKIEES.2025.36.5.457

Range-Doppler map is the principal information that a radar system can acquire from an antenna that is illuminating the target. Radar system can extract the relative range, relative velocity, and signal strength of the target from a range-Doppler map. The distribution of the signal strength varies according to the target shape. Using these characteristics, the radar system can distinguish between the target types. This paper proposes the design of vision transformer-based deep learning network for target classification from a range-Doppler map....

Artificial Structure Detection Based on MSER in SAR Images
SAR 영상에서 MSER을 이용한 인공 구조물 탐지

Jong-Woo Park, Geon Lee, Kyung-Tae Kim 박종우, 이건, 김경태

https://doi.org/10.5515/KJKIEES.2025.36.5.468

In this study, a maximally stable extremal region (MSER)-based detection algorithm is proposed for efficient artificial structure detection in synthetic aperture radar images. The algorithm consists of three stages: First, the MSER algorithm identifies candidate regions of artificial structures and labels them as superpixels to enhance the processing efficiency. This stage reliably detects structures of various sizes and shapes. Second, analyzing the pixel count and average intensity within superpixels distinguishes natural clutter from artific...

In this study, a method for improving the binary classification performance of ships and icebergs using polarimetric synthetic aperture radar (SAR) and deep-learning techniques is proposed. A linear transformation is applied to the polarimetric SAR data to generate hybrid quadrature polarimetric SAR data, which are then incorporated into the existing polarimetric SAR dataset to improve the classification performance. The experiments employed various convolutional neural network models for training, and the performances of the models initialized...

Reconstructing Discarded Signals from FMCW Radar Using Compressive Sensing
압축센싱을 이용한 FMCW 레이다의 손실 신호 복원

Jong-Hun Jang, Jae-Hwan Lee, Bierng-Chearl Ahn 장종훈, 이재환, 안병철

J. Korean Inst. Electromagn. Eng. Sci. 2025;36(5):498-508.
https://doi.org/10.5515/KJKIEES.2025.36.5.498

This study presents a method for reconstructing the target signal of a frequency-modulated continuous-wave (FMCW) radar when it is discarded. The beat frequency spectrum of the FMCW radar is sparse; thus, by applying compressive sensing, a high-dimensional frequency-domain signal can be reconstructed with a small number of time-domain measurements. After discarding the electromagnetic interference signals exceeding the critical value, the entire target signal is reconstructed using a randomly selected portion of the time-domain target signal fr...

This paper proposes an angle estimation technique that has advantages over conventional algorithms in terms of angular resolution, accuracy, and computational speed. This technique, named R-DML, combines the RELAX and deterministic maximum likelihood (DML) algorithms. Its performance was verified through Monte Carlo simulations and measurements using a W-band radar system. In the measurement, the azimuth DOA estimation results for two objects were compared using fast Fourier transform. In the simulation, the root mean square error was compared ...

Angle Estimation Technique Using Multi-Frequency Multi-Beam for Low-Altitude Target Tracking
저고도 표적추적을 위한 다중주파수 다중빔을 이용한 각도추정 방법

Jaehyuk Lim, Euihyuk Lee, Daekyo Jeong, Sunjin Oh 임재혁, 이의혁, 정대교, 오선진

https://doi.org/10.5515/KJKIEES.2025.36.5.518

When tracking low-altitude targets using radar, significant multi-path interference occurs because of their proximity to the sea surface or ground, leading to substantial errors in the monopulse angle estimation. To address this issue, this study proposes the multi-frequency multi-beam (MFMB) technique that combines the multi-frequency and multi-beam approaches. First, an optimal frequency combination is derived using linear regression to ensure that the interference patterns at different frequencies cancel one another out. Subsequently, the re...

Comparison of Spatial- and Frequency-Domain-Based SAR Target Classification Performance
공간 영역 및 주파수 영역 기반 SAR 표적 식별 성능 비교

Seung-Byung Chae, Min-Seok Kang 채승병, 강민석

J. Korean Inst. Electromagn. Eng. Sci. 2025;36(5):528-534.
https://doi.org/10.5515/KJKIEES.2025.36.5.528

This study compares the classification performance of spatial- and frequency-domain-based synthetic aperture radar (SAR) images for target classification. In general, the image in the frequency domain corresponds one-to-one to the image in the spatial domain through Fourier transform; thus, it can be utilized for target classification because the unique information of the target is preserved in the frequency component. A convolutional neural network model was used for SAR target classification, and the moving and stationary target acquisition a...

Harmonic Rejection Single-Side Band CMOS Mixer
고조파 억제 단측파대 특성을 가진 CMOS 믹서

Hyun-Seok Jeong, Byung-Sung Kim 정현석, 김병성

J. Korean Inst. Electromagn. Eng. Sci. 2025;36(5):535-538.
https://doi.org/10.5515/KJKIEES.2025.36.5.535

This study presents a single-side band (SSB) mixer that generates a sinusoidal signal at a frequency f_c − f_b corresponding to a given offset frequency f_b , and an RF sinusoidal signal at f_c. Because generating pulse signals is more cost-effective than generating sinusoidal signals at low frequencies, an offset-frequency signal is applied in the form of the pulse waveform. However, the application of a pulse to a simple switching cor...
