TDWR Scan Strategy Requirements
Summary
Terminal Doppler Weather Radar (TDWR). The report in divided into three main sections:
rationale, example scan strategy and requirements. The rationale for the TDWR scanstrategy
is presented in terms of 1) detection of meteorological phenomena, and 2) minimization of
range and velocity folding effects. Next, an example is provided based on an experimental scan
strategy used in Denver during the summer of 1987. Finally, the requirements for the TDWR
scan strategy are presented based on the preceding discussion. Also, an appendix is included describing the proposed criteria for switching between scan modes.

Recognizing low-altitude wind shear hazards from doppler weather radar: an artificial intelligence approach
Summary
Summary
This paper describes an artificial intelligence-based approach for automated recognition of wind shear hazards. The design of a prototype system for recognizing low-altitude wind shear events from Doppler radar displays is presented. This system, called WXI, consists of a conventional expert system augmented by a specialized capability for processing radar...
Microburst recognition: an expert system approach
Summary
Summary
Expert systems have gained much recent attention as a means for capturing the performance of human experts in specialized fields of knowledge. Areas in which expert systems have been successfully developed include such varied applications as mass spectrogram interpretation, disease diagnosis, geological data analysis and computer configuration (Hayes-Roth et al...
WX1 - an expert system for weather radar interpretation
Summary
Summary
This paper describes work performed by M.I.T. Lincoln Laboratory for the Federal Aviation Administration to investigate the use of expert system techniques for weather radar interpretation. The design of WX1, a prototype system for recognizing low-altitude wind shear hazards from Doppler weather radar data, is presented. The WX1 system consists...
An experimental GPS navigation receiver for general aviation: design and measured performance
Summary
Summary
This report describes work performed by MIT Lincoln Laboratory between 1 October 1979 and 1 March 1983, to evaluate the use of the Global Positioning System (GPS) for low-cost civil air navigation. The report describes a GPS Test and Evaluation System developed jointly by MIT Lincoln Laboratory, Stanford Telecommunications, Inc...
