针对单通道LFM引信欺骗干扰抑制问题,提出了一种基于时频解耦盲分离(TFD-BSS)的干扰抑制算法。该方法首先通过Stretch变换将时频混叠的LFM信号转化为两差频信号,然后利用自适应滤波技术滤出干扰差频信号,并对其进行二次Stretch变换将干扰差频转化为欺骗信号以构造虚拟通道,从而将欠定盲分离转化为非欠定问题,最后通过延时差量法将干扰滤除。实验仿真表明,回波和干扰延时相差5 ns以上即可取得良好的分离效果。该方法不仅可为引信抗欺骗干扰提供借鉴,也是单通道盲分离算法的理论扩展。 相似文献

In recent years there has been much philosophical discussion over the question of whether the prohibitions on markets in such
items as human body parts and gene sequences, and services such as human reproductive labor and sex, should be lifted. Yet
despite the attention paid to this issue there are been surprisingly little discussion of the question of whether markets
in certain items that are currently freely traded should be restricted or eliminated. In particular, there has been little
discussion of the question of whether markets in items that could be readily used to deceive people should be restricted.
I argue in this paper that one of the central moral values of the contemporary West – respect for personal autonomy – requires
that such markets be restricted. 相似文献

In a recent paper that appeared in this journal Fritz Allhoff addresses the morality of bluffing in negotiations1. He focuses on cases in which people misstate their reservation price in negotiations, e.g., suppose that I am selling a house and tell a prospective buyer that $300,000 is absolutely the lowest price that I will accept, when I know that I would be willing to accept as little as $270,000 for the house rather than continue to try to sell it. Allhoff criticizes my (qualified) defense of bluffing in my paper Second Thoughts on Bluffing,2 and offers what he takes to be a more plausible defense of bluffing. Allhoffs criticisms rest on several serious misinterpretations of my views. He ascribes to me several arguments that I dont make. He also attributes to me an unqualified defense of bluffing that I explicitly reject. I briefly document this in Section 1. In Sections 2 and 3 I explain and criticize Allhoffs positive views about bluffing and the morality of bluffing.Thomas Carson is professor of philosophy at Loyola University Chicago.

In the first empirical study on the topic, the authors examined the ability of investment professionals to distinguish between truthful and deceptive statements. A random sample of 154 investment professionals made judgments about a series of truthful and deceptive statements, some of which involved financial fraud. Investment professionals' lie detection accuracy was poor; participants performed no better than would be expected by chance. Accuracy in identifying lies about financial fraud was especially poor. Further, participants displayed poor metacognitive realism when assessing their own performance. The theoretical and practical implications for lie detection in the financial industry are discussed. 相似文献

As businesses become more global, the opportunities for employees to work with individuals from different cultures increase. Research in cross-cultural interactions has increased in response to such changes. This research study considers employee attitudes and perceived organizational support for the use of deception within the work environment. In this study, two types of deception have been considered; deception for personal gain and deception for the organization's benefit. The reported likelihood for committing these two types of deception for United States and Israeli employees was gathered. The results indicate that United States employees are more likely to deceive others for personal gain than the Israeli employees. In addition, the results indicate that United States employees were more likely to perceive organizational support for the use of deception for personal gain than were the Israeli employees. No differences between the two samples were found for personal or organizational support for deception for the organization's benefit. Differences are explained using Hofstede's (1991) theory of international cultures. 相似文献

Recently, it has been argued that the evidence in social science research suggests that deceiving participants in an experiment does not lead to a significant loss of experimental control. Based on this assessment, experimental economists were counseled to lift their de facto prohibition against deception to capture its potential benefits. To the extent that this recommendation is derived from empirical studies, we argue that it draws on a selective sample of the available evidence. Building on a systematic review of relevant research in psychology, we present two major results: First, the evidence suggests that the experience of having been deceived generates suspicion that in turn is likely to affect the judgment and decision making of a non-negligible number of participants. Second, we find little evidence for the reputational spillover effects that have been hypothesized by a number of authors in psychology and economics (e.g., Kelman, H.C., 1967. Psychological Bulletin. 67, 1–11; Davis, D.D. and Holt, C.A., 1993. Experimental Economics. Princeton University Press, Princeton). Based on a discussion of the methodological costs and benefits of deception, we conclude that experimental economists' prohibition of deception is a sensible convention that economists should not abandon. 相似文献

The Escalation of Deception in Organizations 总被引:1,自引:1,他引:0
Drawing on a number of recent high-profile cases of corporate corruption, we develop a process model that explains the escalation
of deception in corrupt firms. If undetected, an initial lie can begin a process whereby the ease, severity and pervasiveness
of deception increases overtime so that it eventually becomes an organization level phenomenon. We propose that organizational
complexity has an amplifying effect. A␣feedback loop between organization level deception and each of the escalation stages
positively reinforces the process. In addition, moderators are proposed that will halt escalation at various stages. By conceptualizing
corporate deception as a social process, the paper contributes to a growing body of research that looks beyond 'bad' individuals
for the causes of corporate illegality.
