With recent advances in low earth orbit (LEO) satellite communication systems, research on deployable antennas, specifically mesh antennas, has been actively conducted. The performance of the mesh antenna can be improved by increasing the opening per inch (OPI), which is a measure of mesh weaving density. However, a higher OPI can also increase cost and weight. Therefore, this study proposes a minimum OPI that achieves the target gain. The results indicate that an OPI of 40 is sufficient to achieve 50 dBi, which is the target gain in this resea...

In this paper, a grill-type leaky waveguide antenna with a high aperture efficiency and power handling capacity, even with an electrically short channel length, is proposed. To obtain the maximum aperture efficiency of the proposed antenna, variations in the antenna radiation performance were observed for the design parameters. The sidewall auxiliary structure design of the designed grille-type leaky waveguide antenna effectively increased the leakage amount to realize an aperture efficiency of 122 % for a single channel, even with an electrica...

In this paper, we describe a ray-tracing method for spherical lenses and reestablish an equation for calculating the radiation pattern using a spherical lens based on previous literature by modifying the physical optics (PO) integral equation. Using this formula, we calculated the radiation pattern according to the size and point source distance of a single-medium spherical lens and a Luneburg lens. While both lenses showed that the beam width became narrower as the lens size increased, the side-lobe level decreased when the source was located ...

PRF Selection Algorithm to Avoid Clutter Doppler Spread
클러터 도플러 확산 회피를 위한 PRF 선택 알고리즘

Chan-Ho Lee, Young-Gwang Seo, Ji-Won Park 이찬호, 서영광, 박지원

J. Korean Inst. Electromagn. Eng. Sci. 2025;36(1):31-37.
https://doi.org/10.5515/KJKIEES.2025.36.1.31

This paper proposes a wave operation algorithm to avoid clutter Doppler spread from surface clutter when the radar tracks low-elevation targets using a pulse train (PT) waveform. The proposed algorithm is a pulse repetition frequency (PRF) selection method to choose an appropriate PRF on which the 'target is not in clutter Doppler spread' from a PRF set. Generally, clutter Doppler spread occurs at a close range. As a result, Doppler spread folding occurs in high-PRF (HPRF) but not in medium-PRF (MPRF). Given this phenomenon, the selection metho...

https://doi.org/10.5515/KJKIEES.2025.36.1.38

When a fighter radar detects an air-to-air target with a medium pulse repetition frequency (MPRF) waveform, if the altitude of the platform is low, the air-to-air target detection range is limited by the sidelobe clutter. A high-pulse repetition frequency (HPRF) waveform, which can detect air-to-air targets in clutter-free areas, can be used to remove the air-to-air target detection range limit caused by sidelobe clutter. We present an HPRF waveform design that uses an M-of-N binary integration for the long-range air-to-air target search/tracki...

This paper proposes a recognition algorithm for the degree of rehabilitation of walking individuals using a Doppler radar sensor. First, the time-series macro velocities of the whole body were estimated by applying a moving average filter and differentiating the phase of the complex signal for the walking individual. Next, the time-series micro velocities of both legs were obtained by subtracting the time-series macro velocities of the entire body from the time-series velocities extracted by applying the conventional method and Kalman filter to...

Non-contact monitoring of oxygen saturation is required to diagnose obstructive sleep apnea, which leads to lethal sleep disorders in adults. This study proposes an estimation algorithm for oxygen saturation using a noncontact radar sensor. First, the algorithm estimates the displacement of the chest, respiratory rate, and cardiac rate using the phase fluctuations of complex signals received from an individual. Next, the pulmonary ventilation, tidal volume, and minute ventilation were estimated using a step-by-step process, leading to the predi...

Postural Compensation Method and Test for Improving Target Angle Measurement Error in High-Maneuverability Aircraft Situations
항공기 고기동 상황에서 표적 각도 측정 오차 개선을 위한 자세 보상 방안 및 시험

In this study, we propose and test a postural compensation method for improving the target angle measurement error in high-maneuverability aircraft situations. To track a target with high tracking accuracy, radars should prioritize technologies that utilize aircraft postural information and target angle measurement error information. If the beam-steering information is calculated with inaccurate postural compensation values, the beam cannot be steered to the desired position. Then, the target can be lost, or incorrect target measurement informa...

This study proposes a method for generating simulated ground clutter signals over randomly rough surfaces in an electronic warfare (EW) environment. In EW scenarios, the receiver captures threat signals that include ground-clutter components, making it crucial to simulate signals that resemble real ground clutter accurately. Previous methods for generating clutter signals have often been limited to specific conditions or relied on empirical data, making generalization difficult. In this study, we applied the Kirchhoff approximation to estimate ...

In modern weapon system design, measuring the radar cross section (RCS) is crucial. However, the establishment of a far-field measurement environment poses significant costs and security challenges. To overcome these limitations, methods that calculate the far-field RCS using image-based near-field-to-far-field transformation algorithms have been explored. However, accurately deriving the RCS requires a large number of near-field measurement samples, which increases the measurement and computation times. This paper proposes an algorithm that ap...

This paper presents the design of an antenna system for F-Scan implementation, enabling high resolution and wide swath (HRWS) capabilities for next-generation SAR satellites. The proposed phased array antenna consists of sub-arrays, each comprising a 1×24 dual-polarized slotted array waveguide antenna with a bandwidth of 1.5 GHz in the X-band. The wide swath width in the F-Scan technique is achieved by enhancing beam squint through phase shifters and true time delay lines (TTDLs) at the maximum electronic beam steering angle along the elevat...
