The elimination of spurious cavity mode is always a problem in coaxial magnetron. The elimination of unwanted cavity mode in a 200 kW X-band coaxial magnetron using lossy dielectric material at suitable places has been discussed and reported. Further the mode separation at higher frequencies is a challenging problem in magnetron. A detail simulation study has been carried out for a 24 GHz, 50 KW fixed frequency rising sun magnetron. All the simulation works have been carried out using commercially available electromagnetic and particle-in-cell simulation code CST Microwave and particle studio. The effort leading toward the system by us has been also discussed.","PeriodicalId":344816,"journal":{"name":"2021 2nd International Conference on Range Technology (ICORT)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127126805","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}

With the help of data association, we obtain the relationship between sensor measurements and existing tracks. Tracking moving targets from a stationary position is likely a potential problem for losing tracks or track mingling. To overcome this problem, we employ a clustering algorithm solution developed using the nearest neighbour technique with the help of an Extended Kalman Filter. This paper focuses on finding out the real-time clustering solution for each target, having at most one measurement from any heterogeneous sensors at a particular timestamp. Here we employ a novel multi-target tracking algorithm using three basic association techniques, i.e. track-to-track association, measurement-to-measurement association and track-to-measurement association. Our real-time data simulation experiments show that the data association algorithm implemented works effectively and gives a good efficiency in real-time multi-target multi-sensor environ-ments.","PeriodicalId":344816,"journal":{"name":"2021 2nd International Conference on Range Technology (ICORT)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127347049","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}

Mobility is one of the defining features of MANET and has a major impact on the performance of routing protocols. In the present work, the performance of the AODV routing protocol is characterised for various mobility scenarios including random movement-based, controlled movement-based and realistic mobility models. A rigorous mobility and scalability analysis of AODV has been presented in graphical form considering transmission delay, number of received packet, control overhead, normalized routing overhead, packet delivery ratio and throughput as the performance measure.

The design includes selection of materials and optimization of layer thickness to operate efficiently in the frequency region of interest. Initially flat plate multilayer analysis and optimization is performed and later this design is transformed into the tangent-ogive shaped radome.

Manual operation which is assigned to individual image features as well as equal weight distribution among themselves creates a matter of concern towards getting better performance.

The objective of the study focuses on the proper weightage assignment to features as per the nature of image. The model has been implemented and tested for the gastrointestinal images containing eight different classes taken from $K_{vasir}$ medical database. The accuracy of the proposed CBIR system is high in terms of Precision and Recall over manual assignment. Hence, this retrieval system for searching similar gastrointestinal images can assist the physicians in identifying accurate gastrointestinal disease.
