In this study, we designed and fabricated a choke antenna as a feeder for a deployable reflector antenna for small satellite spaceborne synthetic aperture radar(SAR). The deep reflector antenna was selected considering the storage efficiency of the deployable antenna, and the number and positions of choke rings were optimized to provide the designed feed antenna with a wide beam width and a proper edge taper of the aperture. The performance of the reflector antenna was analyzed when the designed choke antenna was employed as the feeder. By anal...

Mi Ji Kim, Ji Yoon Han, Su Min Kim 김미지, 한지윤, 김수민

J. Korean Inst. Electromagn. Eng. Sci. 2020;31(1):12-17.
https://doi.org/10.5515/KJKIEES.2020.31.1.12

This study analyzes a method to improve the performance of an ambient backscatter communication system by exploiting the existing radio frequency(RF) signals in cognitive radio environments. More specifically, we propose a power-beacon-assisted method based on spectrum sensing, which determines an operation mode according to the sensing results of a primary system generating the existing RF signals. Through this power beacon, the secondary system transmits using the RF signals of the primary system when it is active, whereas the secondary power...

https://doi.org/10.5515/KJKIEES.2020.31.1.18

In this paper, we proposed a scattering signal model to develop a multi-static passive coherent location(PCL) apparatus using frequency modulation(FM) radio broadcasting. The proposed method first generates in-phase and quadrature(IQ) signals and FM broadcast signals, according to the protocol, and simulates the clutter signal considering the terrain between the transmitter and the receiver. The reflection signal from the target is simulated by considering the time-varying Doppler frequency and radar cross section. The sampling timing of the IQ...

https://doi.org/10.5515/KJKIEES.2020.31.1.26

A multistatic PCL system, known as a passive radar, uses widely available transmitters of opportunity, such as FM radio and mobile communication, to detect a target and localize its position based on TDOA and FDOA between the reference signals and the target echoes. The FM radio signal is mainly used in the multistatic PCL system because of its wide coverage detection capability caused by the high transmitted power of the transmitters. A multistatic system based on the FM radio signal estimates the target’s position based on the TDOA informat...

In this paper, an array antenna with linear and circular polarization characteristics is proposed for 28 GHz band 5G mobile handset applications. A 2×2 slot array antenna is designed for circular polarization in ±z directions; 1×8 and 8×1 dipole array antennas with linear polarizations are designed for 3D beam coverage by fan-beam steering. The proposed antenna is a stacked structure, and all radiating elements are printed on the middle layer of the stacked structure. The −10 dB reflection coefficient bandwidth and 3 dB axial ratio band...

In this paper, we propose a beam operation policy and waveform design method to efficiently detect nose-aspect targets(long-distance threats) using an active electronically scanned array(AESA) radar. The target information to be obtained through the radar beam operation is identified by considering the characteristics of long-range threats/targets, and a beam operation method suitable for target information is designed. This paper presents the design considerations and methods for the efficient acquisition of target information, which is extrac...

https://doi.org/10.5515/KJKIEES.2020.31.1.62

To prevent the detection performance of radar systems from being degraded by interference signals appearing in the side-lobe of the antenna, an additional side-lobe blanking(SLB) antenna is often added and operated alongside the main antenna. In this paper, the SLB antenna composed of array elements within the main antenna is discussed. Using the structural features of the digital active phased array antenna implies that no additional antenna is physically added. Optical channels are also employed to simultaneously form multiple digital beams f...

https://doi.org/10.5515/KJKIEES.2020.31.1.79

Recently, many researches have been conducted on a method of extracting target distance, velocity, and angle information from a radar by detecting a target in real time. Conventional frequency-modulated continuous signal radars have the advantage of higher distance resolution and higher signal-to-noise ratio than pulse radar when detecting a single target. However, when multiple targets are present, Ghost targets are created by the Doppler effect of the reflected signal and cause a false detection problem. In this paper, we introduce a basic fr...
