AK-MADDPG-Based Antijamming Strategy Design Method for Frequency Agile Radar [0.03%]
基于AK-MADDPG的自适应抗干扰设计方法研究
Zhidong Zhu,Xiaoying Deng,Jian Dong et al.
Zhidong Zhu et al.
Frequency agility refers to the rapid variation of the carrier frequency of adjacent pulses, which is an effective radar active antijamming method against frequency spot jamming. Variation patterns of traditional pseudo-random frequency hop...

Luana S Prochazka et al.
Organisms use diverse strategies to thrive in varying habitats. While life history theory partly explains these relationships, the combined impact of resource availability and disturbance frequency on life form strategy evolution has receiv...
Satellite Interference Source Direction of Arrival (DOA) Estimation Based on Frequency Domain Covariance Matrix Reconstruction [0.03%]
基于频域协方差矩阵重建的卫星干扰源波达方向估计方法研究
Jinjie Yao,Changchun Zhao,Jiansheng Bai et al.
Jinjie Yao et al.
Direction of arrival (DOA) estimation is an effective method for detecting various active interference signals during the satellite navigation process. It can be utilized for both interference detection and anti-interference applications. T...
Two-Dimensional Barrage Jamming against SAR Using a Frequency Diverse Array Jammer [0.03%]
基于频移阵列的二维干扰机理研究
Jingke Zhang,Yonghu Zeng,Zongfeng Qi et al.
Jingke Zhang et al.
Due to the modulation of tiny frequency offset on the array elements, a frequency diverse array (FDA) jammer can generate multiple range-dimension point false targets, and many deception jamming methods against SAR using an FDA jammer have ...
Frequency of Device-Related Interruptions Using a Scalable Assessment Tool [0.03%]
采用可扩展评估工具测算的设备相关干扰频率
James C Etheridge,Rachel Moyal-Smith,Christine Lim et al.
James C Etheridge et al.
Background: Surgical devices are implicated in approximately 15% of intraoperative interruptions and 25% of errors. Device-related interruptions (DRIs) are therefore an important target for surgical quality improvement, b...
Microbiome assembly predictably shapes diversity across a range of disturbance frequencies in experimental microcosms [0.03%]
微生物组的组装可预测地影响了在不同干扰频率下实验微宇宙中的多样性
Ezequiel Santillan,Stefan Wuertz
Ezequiel Santillan
Diversity is often implied to have a positive effect on the functional stability of ecological communities. However, its relationship with stochastic and deterministic assembly mechanisms remains largely unknown, particularly under fluctuat...
The effect of target and interferer frequency on across-frequency binaural interference of interaural-level-difference sensitivity [0.03%]
目标音和干扰音频率对双耳相互干扰的影响研究
Beth Rosen,Matthew J Goupell
Beth Rosen
Across-frequency binaural interference occurs when the sensitivity to changes in interaural differences in a target sound is decreased by a spectrally remote diotic interfering sound. For interaural time differences (ITDs), low-frequency (e...
Frequency of icteric interference in clinical chemistry laboratory tests and causes of severe icterus [0.03%]
黄疸对临床化学实验室检测的干扰频率及严重黄疸的原因
Sandhya Mainali,Anna E Merrill,Matthew D Krasowski
Sandhya Mainali
Objectives: The aims of this study were to identify the causes of severe icterus in an academic medical center patient population and to assess the impact of icterus on clinical chemistry testing using assay package inser...
