With increasing treats capability and it's impact ranges, a careful design of Interceptor kill Vehicle with suitable capabilities are very essential. Interception with larger radar biases requires more lateral force from kill Vehicle thus making them heavy, it also requires onboard seeker to have larger target tracking range. In this paper a novel approach is presented to estimates the radar measurement bias by using only one radar which is collocated to interceptor launch location. Here a radar is placed such that it can track both the target missile as well as interceptor missile simultaneously. The onboard interceptor navigation data is fused with the radar measurements to estimate the biases in radar measurements corresponding to target tracks. In this paper a target bias estimation using Extended Kalman Filter is formulated and presented for BMD system. The simulation result shows significant reduction in handing over error which leads to the better kill vehicle design against a high speed targets with technologically feasible Radio Frequency seeker.","PeriodicalId":147815,"journal":{"name":"2019 International Conference on Range Technology (ICORT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130678402","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 study aims at finding the coefficient of drag and shock wave pattern for 155 mm ERFB (BT) artillery shell fitted with recovery plug or with fuze, when travelling at zero angle of attack in a supersonic flow of air. The coefficient of drag (CD0) obtained from the simulation is used as an input parameter for estimation of trajectory elements and preparation of Firing Tables. The numerical results, i.e., the coefficient of drag at different Mach numbers and trajectory elements are validated with the data recorded by tracking radar from an experimental firing. Based on numerical results and data recorded in experimental firing, the coefficient of drag in the case of the shell with recovery plug is compared with shell with fuze. The shockwave in the case of the shell with recovery plug is detached bow shock wave, whereas in the case of a shell with fuze, the shock is attached. The results indicate that the coefficient of drag increases with detached shock wave and an increase in the radius of the shell nose. Good agreements are observed between numerical results and experimental observations. The Firing Table prepared from the study is used in dynamic test and evaluation of armament stores.","PeriodicalId":147815,"journal":{"name":"2019 International Conference on Range Technology (ICORT)","volume":"261 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115012774","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}

Infrared radiometry technology is an important method for characterizing the IR signature of any flight vehicle. It characterizes the distribution of the radiation's power in space. Various atmospheric models are available that describe infrared transmission in atmosphere. Detailed comparison study of actual signature obtained from IR Camera versus the simulated signature generated by JRM Software is done using physical laws and various atmospheric conditions. Thermal signatures of various airborne vehicle have been analyzed using computer vision techniques. A new parameter sigma is introduced which helps to estimate the extinction coefficient. It is combination of two features i.e. intensity and size of detected objects which gives signature. Extinction coefficient is being estimated by fitting an exponential curve to the signature vs. range graph of a test data because signature is exponentially related to range through this extinction coefficient. Finally, it is computed using standard atmospheric conditions prevailing at Chandipur at different time.","PeriodicalId":147815,"journal":{"name":"2019 International Conference on Range Technology (ICORT)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123812253","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 primary aim is to separate the zooming frames from the non-zooming (panning, tilting) frames for which the block motion vector orientation information is modeled utilizing a 3× 3 neighborhood and local tetra patterns. These patterns are binarized followed by feature reduction using the concept of uniform patterns and finally fed to the C-SVM classifier for recognition purposes. Comparative analysis with state-of-the-art methods using ESME and H.264 obtained block motion vectors extracted from standard video sequences show superior performance for the proposed method.","PeriodicalId":147815,"journal":{"name":"2019 International Conference on Range Technology (ICORT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127312567","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 proposed UWB filter consists of a multimode resonator (MMR), which includes a Y-shaped stub loaded on to a half wavelength UIR coupled to the feed lines using ground slots to enhance coupling. Two even modes and one odd mode were generated within UWB band With the aid of two transmission zeros placed at both the lower and upper cut-off frequencies, good selectivity is achieved. A pair of split-ring resonators (SRRs) is placed on either side of a Y-shaped stub to get a notch band within the desired UWB band. Hence, a UWB BPF (working from 3.1 to 10.6 GHz) is demonstrated, with a notch frequency at 5.9 GHz. However, the proposed design shows the wide stopband till 18 GHz with minimum attenuation of 10 dB in all region of stopband. The proposed filter design is verified with a fullwave electromagnetic simulator.","PeriodicalId":147815,"journal":{"name":"2019 International Conference on Range Technology (ICORT)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128100931","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}
