In the paper, a new proposal is discussed to detect the targets in high resolution SAR imagery. First, the improved Lee filter using information entropy is proposed to reduce the noise and keep the detailed characteristic, then a threshold-based segmentation technique is employed to achieve cursory target detection, finally, the feature of target is extracted based on the directed gradient power (DGP). After above operation, the target is accurately detected. And the measured data is used to validate the effectiveness of the method.","PeriodicalId":394548,"journal":{"name":"2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131035697","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}

The basis of the generator is an avalanche transistor and a unique pulse forming circuit, which forms ultra-wideband balanced Gaussian pulses. The unique pulse forming circuit utilizes the performance of the SRD effectively to generate a couple of balanced narrow pulses with high pulse repetition frequency (PRF) up to 1MHz. A simple avalanche transistor driver is also described, which transforms a trigger signal to a driving pulse with the timing and amplitude parameters required by the SRD. After optimizing the circuit parameters and the bias conditions of the pulse generator, the design can generate a couple of balanced ultra-short electrical pulses with the peak output voltages of approximately 30V at 100 kHz PRF and the output pulse width FWHM (Full-Width at Half-Maximum) of approximately 250 ps. As the power dissipation of this generator is very low that it is used for application in near-field UWB radar sensors.","PeriodicalId":394548,"journal":{"name":"2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133315898","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 implements their online identification through calculating the fuzzy nearness between the energy distribution of the measured signal and the eigenvector.

In order to realize microminiaturization of optical current transformer, sensing structure must be simplified first. Considering measure performance and material character, straight light path type optical current transformer which is made of block glass is the simplest structure. The Faraday optical rotation curve which reflects the relationship between Faraday angle and magneto-optical material length has been obtained. This paper has put forward a simple algorithm of knee point, which could fix the knee point on curve fleetly. The magneto-optical material length on knee point has a highest utilization ratio. According to the research, knee point position is related with glasses location and sectional shape of conductor. So the best location is the place nearest to conductor.","PeriodicalId":394548,"journal":{"name":"2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132268409","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}

There are many methods to calculate trust of peer who has direct interaction, but there are few methods for indirect interaction peers.

Waveform design is a principal important issue before radar imaging successfully in MIMO. There are two main requirements for the waveform used in MIMO radar imaging: the signals should be orthogonal and its auto-correlation function should have low side lobe noise and narrow main lobe. This paper analyses statistical characteristics of random stepped frequency (RSF) signal's auto-correlation deeply and proves that large stepped frequency number is suitable for MIMO imaging radar. Then a method for designing random stepped frequency-coding waveforms by modified genetic algorithm is presented here. A random matrix is used for initializing the genetic algorithm, and annealing algorithm is applied here for avoiding GA's disadvantages such as prematurity. In the end we compare the waveforms designed by GA and MGA and apply the waveforms in MIMO radar imaging simulation, the result proves that it is suitable for overcoming interfere among MIMO radar channels and imaging target.","PeriodicalId":394548,"journal":{"name":"2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127872588","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}

In this paper, a single-channel method based on multi-resolution wavelet is proposed. Multi-resolution wavelet is involved in decomposing and reconstructing the signal, so that the envelope of signal spectrum can be extracted. Then, calculate the required gain of each feature point. After that, the gain of entire signal spectrum is obtained by interpolation algorithm. Experiments show that the proposed algorithm can not only compensate the loudness of speech, but also effectively protect the speech feature, which improves the speech recognition rate.","PeriodicalId":394548,"journal":{"name":"2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"239 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133852982","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}
