Download or read book Coherent Seeker Guided Antiship Missile Performance Analysis written by and published by . This book was released on 2005 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance capability of an antiship missile's radar guidance system can be rated by the ratio of the processed signal level to the interference or noise level. In this report, the general performance capability is evaluated for missiles guided via noncoherent radar and for missiles guided via coherent radar. The contribution of several coherent aspects are compared including interpulse, intrapulse, and beam sharpening. Potential improvement of as much as 15 to 20 dB are indicated. A brief derivation of a useful representation of the processed signals is presented that describes the potential usefulness of Space-Time Adaptive Processing.

Download or read book The Evaluation of Radar Guided Missile Performance Using Various Target Glint Models written by Franklin Delano Hockett and published by . This book was released on 1970 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A radar guided missile seeker approaching a target arrives at a crossover point beyond which the entire target is illuminated by the missile seeker's radar antenna beam. When this occurs, for a complex target, the radar senses a time changing target center location which may greatly complicate the terminal tracking portion of the seeker's flight. This thesis documents various glint models in use today and compares the performance of these models by using a seeker model to determine the effect of glint on terminal tracking performance. A large volume of data has been compiled describing various radar characteristics of complex targets. Some of the glint models discussed herein are the result of independent investigations and some models are derived analytically. The return energy transmitted from a radar and reflected from a complex target is generally statistical in nature due to the random nature of the reflecting surfaces dispersed over the target vehicle and also because the target is continually changing aspect. A radar target's reflecting characteristics are of concern when a seeker is attempting to acquire the target and again when the seeker is closing on the target. A large amount of data exists for determining long range acquisition capabilities of various radar schemes. The acquisition of a target in a sea clutter background has been thoroughly investigated in the past decade and today's improved techniques (Moving Target Indication and Pulse Compression) have enabled moderately powered radars to acquire very small targets in high sea states. At long ranges, the individual target elements present a unified amplitude response (or appear as a point source). The main problem during acquisition is to reduce the viewing area to dimensions comparable to the target so that the target return will be distinguishable. This argument does not apply to an interferometer as target phase variations will still contribute to acquisition error, however the sophistication required to implement interferometers into a seeker design precludes their use for present day tracking schemes. Although acquisition problems can severely limit the response time of a seeker bearing vehicle or aircraft to an eminent attack threat, the inability of a radar seeker to operate in the presence of angle glint can render the seeker useless. A seeker's design must often be a compromise between tracking accuracy, acquisition capability, and dynamic versatility, since the weight and cost penalties associated with multiple radar tracking modes within a single seeker are prohibitive. Therefore, since the literature abounds with acquisition theory and techniques, the main portion of this thesis consists of analyzing the post-acquisition seeker performance in the presence of angular glint or angle noise. The glint models used in this analysis represent models in use at the present time. In addition, models which were derived are compared to determine the degree of correlation which exists between measured target models and those models which are derived from their statistical characteristics. The method employed for the evaluation is general in nature so that the procedure could be used to evaluate any subsequent glint model derivations. In addition, some recent work is summarized which demonstrates the advantages of using swept frequency techniques to improve radar tracking performance in the presence of angular glint"--Abstract, pages ii-iv.

Download or read book Chinese Anti Ship Ballistic Missile ASBM Development written by Andrew S. Erickson and published by Brookings Institution Press. This book was released on 2016-08-02 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: China’s anti-ship ballistic missile (ASBM), the DF-21D, has reached the equivalent of Initial Operational Capability. Although it probably has been deployed in small numbers, additional challenges and tests remain. This study examines the ASBM’s capability and history, showing how the DF-21D meets multiple priorities in Chinese defense modernization and in the national security bureaucracy, as well its implications for the United States. The ASBM’s physical threat to U.S. Navy ships will be determined by the development of associated systems and organizations, which currently limit data fusion and coordination in the complex task of identifying a U.S. aircraft carrier in the open ocean. Still, the ASBM poses a direct threat to the foundations of U.S. power project in Asia and will undermine the U.S. position, unless efforts to counter its political-military effects are taken.

Download or read book Low Angle Radar Land Clutter written by J. Barrie Billingsley and published by William Andrew. This book was released on 2002-04-01 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: A necessary reference for all radar engineers or analysts including many levels of managers, advisors and decision makers in the U.S. and worldwide radar industry. Directly useful in both military (DOD) and civilian (FAA) applications. The result of 20 years of research at MIT Lincoln Lab, this book is of the most significant tehcnological consequence for the industry. It actually solves the problem of low angle radar land clutter by showing the reader how to design and predict the performance of radars that operate in situations where land clutter prevalent. Radar land clutter constitutes the unwanted radar echoes returned from the earth's surface that compete against and interfere with the desired echoes returned by targets such as aircraft and other moving and stationary targets. The ability to accurately predict the effects of land clutter in surface radar has been an unsolved problem for many years. This book is comprehensive in addressing the topic, containing many interrelated results, each important in its own right. It unifies and integrates all the results so as to create a comprehensive, innovative, and unequaled work. The results of this book directly enable the reader to predict land clutter effects in surface radar. Modern military aircraft deliberately fly low to hide their presence from radars that are also dealing with land clutter. Depending on the terrain, the performance of the radar varies greatly from very good to very poor. This book helps radar engineers provide accurate assessments of ground clutter, thus bringing their ability to detect and operate against low flying aircraft to a much higher and much more consistent level.

Download or read book China s Strategic Modernization Implications for the United States written by Mark A. Stokes and published by DIANE Publishing. This book was released on with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional wisdom portrays the People's Republic of China (PRC) People's Liberation Army (PLA) as a backward continental force that will not pose a military challenge to its neighbors or to the United States well into the 21st century. PLA writings that demonstrate interest in exploiting the revolution in military affairs (RMA) are dismissed by a large segment of the PLA- watching community as wistful fantasies. The author offers an alternative perspective by outlining emerging PLA operational concepts and a range of research and development projects that appear to have been heavily influenced by U.S. and Russian writings on the RMA. Fulfillment of the PLA's vision for the 21st century could have significant repercussions for U.S. interests in the Asia-Pacific region.
