This book was released on 1970 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pennsylvania Research Associates Inc. (PRA) has assisted the Naval Training Device Center (NTDC) in the demonstration of a radar landmass simulator which displays culture data in real time. The report describes those additions, both hardware and software, which will include the effects of natural terrain. The hardware includes a matrix of 72 analog multipliers, called the MULTRIX, which evaluates a Lagrange polynomial region by region in real time. The errors in the analog implementation are shown to be composed of a random component due to the finite width of tolerance bands on the analog elements, and a fixed dc (drift) component due to uncompensated temperature changes.

This book was released on 1970 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pennsylvania Research Associates Inc. (PRA) has assisted the Naval Training Device Center (NTDC) in the demonstration of a radar landmass simulator which displays culture data in real time. The simulator employs a general-purpose digital computer operating on digitally stored data. The radar video signal is produced through selected hybrid equipment, including a scan conversion tube. The report describes in detail the computer programs prepared by PRA for operation of the system at the Phase 2 stage of development. These include a special multiprogramming control program, a simplified flight simulator, and the radar picture manipulation programs. (Author).

This book was released on 1969 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present report applies to the second and third phases of a four-phase program implementing the real-time radar simulator. Phase 3 covers presentation of dynamic displays of terrain data in addition to the culture data displayed in Phase 2. Only those areas in which the Phase 3 system affects the Phase 2 system are discussed. The Phase 2 system is designed to add the Phase 3 system in a modular fashion; this report describes the hardware and software to do so. (Author).

Book excerpt: Previous work performed by Pennsylvania Research Associates Inc. for the United States Naval Training Device Center demonstrated the technical and economic feasibility of a radar landmass simulator using a general-purpose computer. The computer operates on digitally stored data, and, through selected hybrid equipments including a scan conversion tube, produces the radar video signal. The present report is the final report under this contract. It summarizes the system design presented in previous reports. In addition, it describes the preparation of the culture data for the simulator. The data was digitized from maps and then joined together by means of a computer program. Finally some experiments on region size to determine the adequacy of PRA methods of terrain representation to handle long ranges were performed and the results reported here.

Available in PDF, EPUB and Kindle. Book excerpt: Project 1183 was designed as an engineering development model to demonstrate the effectiveness of digital radar landmass simulation and to establish a technological baseline from which future high resolution Digital Radar Landmass Simulators (DRLMS) can be developed. Among the goals of this project were: to demonstrate the feasibility of high resolution radar landmass simulation; to develop, concurrently, a digital data base; to be an engineering test bed for the development of specifications for future Air Force radar simulators; and to gather data about interfacing a DRLMS to an existing mission simulator.

This book was released on 1964 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents a logical design of a natural terrain radar land mass simulator, techniques for incorporating radar effects, and cultural terrain into the simulator, and relationship between simulator design and specific operational requirements. The results of this work indicate that the techniques developed are feasible from an engineering standpoint but are impractical due to cost considerations. A firmer understanding of the information content of maps and digital representation techniques must be established to compress the data to a degree whereby an economically feasible device can be developed.

Download or read book Simulation of a Digital Radar Landmass Simulator written by Roger M. Derby and published by . This book was released on 1973 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report summarizes work in simulating the Digital Radar Landmass Simulator (DRLMS) for evaluation purposes. The software produced under this contract is run on a computing facility to generate simulated radar images on a radar display. The work done consisted of two parts: production of a data base and simulation of the hardware's processing of this data base. In development of the data base, the contractor compressed government-supplied data, in a grid format, to an 'edges' representation. The edges are ridge and valley lines, in the case of terrain data, and reflectance boundaries for culture data. The algorithms used to achieve this representation are not to be construed as 'optimum'. They are, however, vehicles for studying a technique and can be easily modified by the user if desired.
