We show that the design meets the specific requirements upon wave-form design that arise from the operation of a satellite-borne precipitation radar. The error performance is evaluated in terms of both slow and fast varying errors on phase and amplitude. We illustrate the effect of errors with modified data from a real system.","PeriodicalId":339522,"journal":{"name":"2006 International Waveform Diversity & Design Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125321395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And the basic concept derived from these principles is that if one has multiple copies of the same system, presumably one would have a better chance of achieving the desired goals. The fundamental problem with this simplistic way of reasoning is that one needs to understand the physical environment where such an experiment needs to be carried out and how one should interpret the final result. The current state of the art applies some statistical framework to the physical scene to explain the added advantage of diversity. To appreciate the true physical significance of diversity we have to go back to the roots! We need to understand first what the statistical framework implies and secondly how it relates to the problem at hand. So we need to address the following questions: 1. Who first introduced the concept of ensemble averaging in physics and in what context? 2. What is the physical significance of ensemble averaging?","PeriodicalId":339522,"journal":{"name":"2006 International Waveform Diversity & Design Conference","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125500662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these are also microwave sources, which can reach extensive peak power of up to Pmax = 250 MW. Solitary, in some cases several times repeated, impulses lasting from tp ∊ <1, 60> ns, cause the destruction of semiconductor junctions. The problem of security support of the air traffic, transportation, computer nets, banks, national strategic data centers, and other applications crops up.

Waveforms based on mutual information between a target ensemble and the received waveforms, under time and energy constraints, have already been determined. They are applied to the M-target ID problem, and compared with the solution obtained by maximizing the average distance between hypotheses. A single illumination is considered first with regard to the binary and the M-ary target ID problem. A new iterative transmission scheme is proposed that calculates the probability of each hypothesis and updates the transmission waveform at each step. This is coupled with a sequential multi-hypotheses testing procedure and shown that for the same error rate, the proposed iterative scheme combined with an information-based waveform can reduce the number of iterations to reach a decision.","PeriodicalId":339522,"journal":{"name":"2006 International Waveform Diversity & Design Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116989494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing the number of active users in the multiple-access channel increases the multiuser interference. To minimize the degradation, the number of iterations is usually increased at the cost of additional latency. In this paper, it is shown that message authentication with or without encryption when implemented with Turbo MUD, decreases the number of iterations required for optimal detection and also improves the performance.","PeriodicalId":339522,"journal":{"name":"2006 International Waveform Diversity & Design Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115191060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been argued that receivers in multisite radar can be treated as passive sensors and hence the bearing locationing estimation can be applied to these radars as well. An example of a system with two receiver antennas is studied as being analogous to two passive sensors. Area of error region is also estimated based on a point target model as well as a realistic distributed target model and the probabilistic distribution of detection region with receive look angles is determined. It is noted that certain cut angles are very undesirable and should be avoided while planning the positioning of the receiver antennas, while there are angles which yield high detection.","PeriodicalId":339522,"journal":{"name":"2006 International Waveform Diversity & Design Conference","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122812941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One algorithm uses an iterative least squares approach to form a hybrid waveform that simultaneously maximizes SINR and minimizes peak side-lobe levels under the constraint of constant signal amplitude modulus. A second algorithm employs a simple modification to the traditional Costas coded signal that increases SINR while maintaining a constant modulus and its ideal ambiguity function. Another algorithm makes use of four peak-sidelobe preserving properties inherent to biphase codes to choose the biphase modulated signal having the smallest Euclidean distance from the SINR-optimal signal. These algorithms are tested in a variety of interference scenarios, including wide band and narrow band interference sources as well as realistic terrain scattered interference settings. Findings from these tests are presented in terms of SINR gain over an ordinary linear frequency modulated pulse and autocorrelation sidelobe suppression.","PeriodicalId":339522,"journal":{"name":"2006 International Waveform Diversity & Design Conference","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117006822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
