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.

Book excerpt: The purpose of the in-house Radar Landmass Simulation (RLMS) project is to develop a research tool for study in the area of digital radar training devices. The tool should help one to determine an optimum specification for procured hardware and to define the training requirements, offer a means of evaluating proposed hardware schemes through simulation of the proposed schemes, and be capable of producing a simulated radar scope display in simulated real-time. Finally, the research tool should be easily changeable to facilitate experimentation. The report contains a general description of the hardware and software which has been developed, with emphasis on the results obtained. The appendices contain detailed schematics for the hardware, flowcharts and listings for the software.

Available in PDF, EPUB and Kindle. Book excerpt: To generate input data with a 50-foot resolution and fifteen shades of gray for advanced high-resolution digital radar simulators, this research examined and defined data sources and processing techniques. Limited to the Continental United States and to unclassified information, the data sources included all known aerial mapping imagery and topographic maps. All existing image processing techniques and devices were examined to define their operating principles. This review led to the conclusion that adequate geometric information for radar simulation data could be extracted from the current data sources and that existing processing capabilities could be combined into a feasible automatic system. In related work, non-parametric three-dimensional resections were calculated on a digital computer, and mathematical concepts were developed to give a computer system the capability of interpreting the physical characteristics in photos by using cues as done by a trained photo interpreter.

Download or read book Radar Landmass Simulation Computer Programming Interim Report written by Craig K. Brown and published by . This book was released on 1973 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several methods have been devised for processing a digital radar data base to create simulated mapping-radar scope images. To aid in the evaluation of these various methods, NAVTRAEQUIPCEN has developed a system which operates in conjunction with its TRADEC System to produce a pseudo real-time radar display. Simulation methods can be simulated on this system for comparison and evaluation. The objective of this report is to describe the software, developed in-house, which processes raw digital radar data to produce a 'baseline' simulation against which other methods may be compared. The software is functionally broken down into three tasks: terrain data processing, cultural data processing, and radar effects. It is written in a high-level language, FORTRAN, to facilitate experimentation and modification. (Author).

This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the extent to which digital computing techniques may afford improved performance in the realtime simulation of airborne radars is reported. It is desired to reproduce the display presented by a scanning, groundmapping radar, having a range in the order of 200 miles and a resolution in the order of 60 points per mile. The simulated radar is mounted in an aircraft that flies at a maximu speed of Mach 3 at any altitude up to 10 miles, the flight plan not known to the simlator in advance. While a cursory examination of such requirements indicates that a straight-forward digital computer simulation of the display waveform would require exorbitant memory sizes and tremendous computational speeds, many factors can be used to advantage, in order to reduce the computational complexity to economically manageable proportions. Redundancy in the terrain itself implies that the height and reflectivity observed by the radar are not purely random functions; their consistency or predictability can be shown to significantly reduce the information-handling capacity of a simulator.

This book was released on 1982 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper deals with a semi-automatic, interactive system to generate data bases from Digital Landmass System (DLMS) Data, for Computer Generate/Image Visual Systems (CGIVS) and for Digital Radar Landmass Simulation (DRLMS) Systems. Terrain information and certain culture features can be gained from DLMS data automatically for CGVIS and DLRMS data bases. Additional information is prepared by interactive methods, including the use of model library for CGI data bases developed by batch procedures. Data bases can also be developed solely by batch procedures.

This book was released on 1968 with total page 89 pages. Available in PDF, EPUB and Kindle. 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 composed of a general-purpose digital computer. The computer operated on digitally stored data, and, through selected hybrid equipments, including a scan conversion tube, produced the radar video signal. The report applies to the second phase of a four-phase program implementing the real-time radar simulator. Phase 2 covers presentation of dynamic displays of cultural data, using a scan converter system and a large-scale general-purpose digital computer. The report describes the mathematical aspects of the radar model and specifically details the hardware and software required to construct the Phase 2 system. (Author).
