| Abstract | Based on modified rank test, this paper proposes two new nonparametric detectors by using the K-distributed sea clutter model. These two detectors are Modified-Rank-based Generalized Sign detector (MRGS) and Modified-Rank-based Mann-Whitney detector (MRMW). The new detectors are achieved by designing the inverse-normal-score functions of the rank statistics. They are CFAR (Constant False Alarm Rate) for the data with continuous CDF (Cumulative Distribution Function) and with PDF (Probability Density Function) bing symmetric about zero. The performance of the new detectors is analyzed under the Swerling II target model by Monte-Carlo simulation. We compare the results of our proposed detectors with two classical nonparametric detectors: Generalized Sign (GS) detector and Mann-Whitney (MW) Detector. The most important conclusion is that the detectability of nonparametric detector is insensitive to the change of the scale parameter b but just depends on the shape parameter v of the K-distributed clutter for the Swerling II target model. Moreover, nonparametric detector especially for the proposed MRMW detector in this paper is quite suitable for low observable targets detection under spiky K-distributed sea clutter. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
