However, the design of many existing surveillance radar systems is such that the development, proving and implementation of even the smallest algorithmic changes can require costly and time-consuming equipment modifications. In the design of future radar systems there is therefore a strong case for the use of a programmable processor which is separated from the microwave hardware by a clearly defined interface. This paper presents some results from a research programme which has developed such a rapid prototyping environment by interfacing an existing in-service airborne maritime surveillance radar to a commercially available computer workstation and a high-bandwidth tape recorder.","PeriodicalId":127784,"journal":{"name":"Electronics & Communication Engineering Journal","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122263624","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}

When an armed force is deployed, frequencies must be assigned, within a restricted bandwidth and in a short time-scale, to its many (e.g. 400) radios so as to minimise the interference between them. There are too many ways in which a frequency allocation can be made for them all to be evaluated; instead the best assignment that can be discovered within a limited time must be chosen. This is typical of a class of problems known as combinatorial optimisation problems. This paper discusses some of the methods which can be used for solving such problems and presents results for a hybrid algorithm based on construction methods, tabu search and genetic algorithms which has been developed at DERA-Malvern.","PeriodicalId":127784,"journal":{"name":"Electronics & Communication Engineering Journal","volume":"431 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123441160","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 main function of these error-resilient techniques is to reduce the propagation of errors within the decoded data. Two main techniques are discussed in detail: the error-resilient entropy code (EREC) and pyramid vector quantisation (PVQ). The paper concludes with a comparison of the relative merits of these systems and areas for further consideration.","PeriodicalId":127784,"journal":{"name":"Electronics & Communication Engineering Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124307052","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}
