| 1 | Jamming de-chirping radar using interrupted-sampling repeater显示文摘Interrupted-sampling repeater jamming (ISRJ) is a novel jamming mode for pulse compression radar in principle.In this paper,a jamming approach of applying ISRJ to de-chirping radar is presented.The principles of ISRJ are expounded,and the ways to achieve a train false target for de-chirping radar are analyzed.The characteristics of false target,including time-domain characteristic,frequency-domain characteristic and amplitude characteristic,are described.Based on this,the power requirement for jammer is put forward and the key elements that determine the space distribution location between true and false targets are discussed in detail.At last,simulation results are presented and addressed.This work is beneficial to the jamming design and use of ISRJ. | FENG DeJun TAO HuaMin YANG Yong LIU Zhong | 2011 | Science China(Information Sciences)2011，54，10： | 35 |
| 2 | Passive source range estimation with a single receiver in shallow water显示文摘An approach for long-range passive impulsive source ranging with a single receiver in shallow water is proposed,which utilizes the frequency spectrum of the warped signal autocorrelation function via warping transform.For an ideal waveguide,there are invariable frequency features both in the frequency spectrum of the warped signal corresponding to modal cut-off frequencies and the warped signal autocorrelation function due to modal interference.These intrinsic frequency features can be used to passive source ranging.So,the approximate relationship between the frequency of warped signal at an unknown source range and the intrinsic frequency extracted by the time warping transform is derived.These rules can be generalized to an actual shallow water waveguide.Employing an acoustic model to offer the invariable frequency spectrum features,the impulsive signal data collected by a single hydrophone in the North Yellow Sea in December 2011 are analyzed to verify the proposed source ranging approach.The estimated ranges are in good agreement with the ranges measured by GPS,and the mean relative error of range estimation is less than 10%. | QI Yubo ZHOU Shihong REN Yun WANG Dejun LIU Jianjun FENG Xiqiang | 2015 | Chinese Journal of Acoustics2015，34，1： | 13 |
| 3 | Optical fiber SPR biosensor complying with a 3D composite hyperbolic metamaterial and a graphene film显示文摘In the present study, an optical fiber surface plasmon resonance(SPR) biosensor was developed for measuring time-and concentration-dependent DNA hybridization kinetics. Its design complies with a 3D Au∕Al2O3 multilayer composite hyperbolic metamaterial(HMM), a graphene film, and a D-shaped plastic optical fiber.According to the numerical simulation and the experimental demonstration, the SPR peak of the designed biosensor can be effectively altered in the range of visible to near-infrared by varying the HMM structure. The sensitivity of the appliance was shown to achieve a value of up to 4461 nm/RIU, allowing its applicability for bulk refractive index sensing. Furthermore, a biosensor designed in this work displayed high-resolution capability(ranging from 10 pM to 100 nM), good linearity, and high repeatability along with a detection limit down to 10 pM, thus suggesting a vast potential for medical diagnostics and clinical applications. | Can Li Jinjuan Gao Muhammad Shafi Runcheng Liu Zhipeng Zha Dejun Feng Mei Liu Xuejian Du Weiwei Yue Shouzhen Jiang | 2021 | Photonics Research2021，9，3： | 3 |

| 19 | Simulation of two-dimensional ISAR decoys on a moving platform显示文摘It is potentially useful to perform deception jamming using the digital image synthesizer(DIS) since it can form a two-dimensional(2D) decoy but suffers from multiple decoys generation. Inspired by the intermittent sampling repeater jamming(ISRJ), the generation of inverse synthetic aperture radar(ISAR)decoys is addressed, associated with the DIS and the ISRJ. Radar pulses are sampled intermittently and modulated by the scattering model of a false target by mounting the jammer on a moving platform, and then the jamming signals are retransmitted to the radar and a train of decoys are induced after ISAR imaging. A scattering model of Yak-42 is adopted as the false-target modulation model to verify the effectiveness of the jamming method based on the standard ISAR motion compensation and image formation procedure. | Xiaoyi Pan Wei Wang Qixiang Fu Dejun Feng Guoyu Wang | 2015 | Journal of Systems Engineering and Electronics2015，26，2： | 1 |
