An extraction method is proposed for the equivalent circuit parameters of an X-band PIN diode based on waveguide measurement. For the S-parameter measurement, a network analyzer, a waveguide, a transition, two identical adapters, and a 1×2 unit cell with two PIN diodes were used, and the equivalent circuit parameters of the PIN diode were extracted from the measurement results. The thru, reflect, line calibration method was adopted to reduce undesired errors in the components used for measurement, and the equivalent circuit ...

https://doi.org/10.5515/KJKIEES.2022.33.8.591

In recent years, efforts have been made to replace rod-shaped monopole antennas with planar antennas exhibiting an omnidirectional radiation pattern. In this paper, we describe the design, fabrication, and testing procedures of a dual-band planar antenna that can replace a monopole antenna used in wireless local area network (LAN) routers. The proposed antenna consists of a square metal patch, square ring, and shorting vias on a multilayer printed circuit board to induce 2.4 GHz and 5 GHz dual-band resonance and omnidirectional radiation patter...

A power amplifier structure is presented that has a low output power variation against the load impedance variation at 6.78 MHz using two Class E power amplifiers and a λ/4 transmission line. A Class E amplifier with a low output impedance and another Class E amplifier with a high output impedance are connected in parallel with a phase difference of 90° using a λ/4 transmission line. Each amplifier generates the same output power under nominal load conditions to achieve the maximum efficiency. The output pow...

Ultrawideband (UWB) wireless communication technology, which appeared 20 years ago, is becoming popular in various fields because the ability to measure the precise distance between UWB devices beyond wireless communication is being re-examined. The currently commercialized UWB technology is high-rate pulse repetition frequency (HRP) UWB technology, which uses high-speed UWB pulses of several tens of megahertz, and precise distance and direction measurements are made by using the characteristic changes of the channel impulse responses (CIRs).

For an electromagnetic plane wave that is normally incident upon an aperture or aperture array in an infinite perfectly electrical conducting plane, the validity of the general expression for the transmission cross-section as a measure of the transmitted power through the aperture or aperture array is investigated for the following two cases: first, for a single transmission resonant aperture (TRA) such as a complementary split ring resonator, which is larger than Bethe’s small magnetic dipole; second, for the finite periodic array of a non-T...

Airborne Monopulse Radar Echo Signal Generation from Surface Clutter Including Weather Clutter Effect
기상 클러터 효과를 고려한 표면 클러터 반사신호 모노펄스 레이다 공대지 신호 생성

Jihyo Choi, Il-Suek Koh, Ji-hyun Jung 최지효, 고일석, 정지현

https://doi.org/10.5515/KJKIEES.2022.33.8.626

An airborne radar echo signal includes signals returned from clutter and a target; thus, simulating the signal from the clutter may be crucial for predicting and analyzing accurate radar performance. Because it can be extremely difficult and expensive to obtain real measured signal data for various scenarios, an accurate signal generation method is required. Existing weather clutter and ground clutter simulators for an X-band airborne radar are combined to simulate the echo signal when two clutters exist simultaneously. The weather clutter effe...

Ground Moving Target Tracking Using TWS on Airborne AESA Radar
항공기 AESA 레이다에서 TWS를 이용한 지상 이동 표적 추적

Won-Jun Lee 이원준

J. Korean Inst. Electromagn. Eng. Sci. 2022;33(8):635-643.
https://doi.org/10.5515/KJKIEES.2022.33.8.635

A target-tracking method using the ground moving target indicator (GMTI) mode on active electronically scanned array (AESA) radar is proposed. The GMTI mode can operate in wide ground areas. However, the 3-dB beamwidth of the X-band radar is narrow, and a target is detected on multiple adjacent beams. To delete overlapping target plots, beam-to-beam processing considering a real-time system is proposed. In addition, a track while scan (TWS) multiple-target-tracking algorithm was constructed for the system. Through a flight test with true car mo...

Radar Elevation Angle Correction Using Parabolic Equation Method
포물형 방정식을 이용한 레이다 안테나 고도각도 보정 연구

Jun Heo, Young-Kwang Seo, Min-Kyu Park, Joonwoo Bae, Yong Bae Park 허준, 서영광, 박민규, 배준우, 박용배

https://doi.org/10.5515/KJKIEES.2022.33.8.644

A radar system transmits radio waves and interprets the returned signal to perform a specific function. Radio waves traveling between the radar and an unknown target are affected by refraction as they travel through the atmosphere, which increases the possibility of errors in the interpretation of the results when the radar is operating. If it is possible to predict the extent to which radio waves are affected by refraction, this capability can be applied to radar operation to direct radio waves to an area where an unknown target is likely to b...

https://doi.org/10.5515/KJKIEES.2022.33.8.649

When detecting targets of interest in satellite synthetic aperture radar (SAR) images, clustering is often required to construct the candidate pixels of an object. In this paper, we propose a new feature using principal component analysis to address the problem of dense targets that cause performance degradation when using the density-based spatial clustering of noise algorithm, which is suitable for the clustering process. Further, simulations are used to analyze the proposed features for different target and clutter clusters extracted from re...
