研究室紹介
Professor Seong-Ook Park's research lab specializes in advanced wireless communication systems and microwave engineering, with a focus on body-centric communication, synthetic aperture radar (SAR) signal processing, and broadband antenna design. The lab develops innovative transceiver systems for human body communication using spread spectrum techniques and explores advanced signal processing methods such as fractional Fourier transform for moving target detection in Video-SAR. It also designs compact, high-performance antennas—like rhombic slot antennas on foam substrates—tailored for satellite and mobile communication applications. The lab emphasizes practical, low-cost solutions with high sensitivity and wide bandwidth.

4This paper presents a transceiver module for human body communications whereby a spread signal with a group of 64 Walsh codes is directly transferred through a human body at a chip rate of 32 Mcps. Frequency selective digital transmission moves the signal spectrum over 5 MHz without continuous frequency modulation and increases the immunity to induced interference by the processing gain. A simple receiver structure with no additional analog circuitry for the transmitter has been developed and ha
In the field of synthetic aperture radar (SAR), a lot of researchers have tried to study an improved application beyond the conventional two-dimensional image. Video-SAR (ViSAR) is one of the hot issue in the SAR application. The main purpose of ViSAR is to monitor various targets in the area of interest in time order. It can offer video images to detect not only the fixed target but also the moving target. For the signal processing of ViSAR, this article introduces the improved performance by t
This paper presents the rhombic slot antenna that has a broadband characteristic by using a low cost foam-substrate. The feed line is embedded in the middle of the triplate to prevent unwanted and spurious radiation. The proposed rhombic slot antenna has a rectangular patch with supplementary section to improve the impedance bandwidth performance. Experiments using a 2/spl times/1 array antenna are performed to validate the simulation. A bandwidth of 40% can be achieved. The electrical character
