Digital correlation of DDRS data
The reduction of digital SAR (synthetic aperture radar) data to radar images for use in remote sensing applications was investigated. The critical software operations are discussed in detail, and suggestions and recommendations are made for improving the algorithms currently being used
Development of a ground signal processor for digital synthetic array radar data
A modified APQ-102 sidelooking array radar (SLAR) in a B-57 aircraft test bed is used, with other optical and infrared sensors, in remote sensing of Earth surface features for various users at NASA Johnson Space Center. The video from the radar is normally recorded on photographic film and subsequently processed photographically into high resolution radar images. Using a high speed sampling (digitizing) system, the two receiver channels of cross-and co-polarized video are recorded on wideband magnetic tape along with radar and platform parameters. These data are subsequently reformatted and processed into digital synthetic aperture radar images with the image data available on magnetic tape for subsequent analysis by investigators. The system design and results obtained are described
APQ-102 imaging radar digital image quality study
A modified APQ-102 sidelooking radar collected synthetic aperture radar (SAR) data which was digitized and recorded on wideband magnetic tape. These tapes were then ground processed into computer compatible tapes (CCT's). The CCT's may then be processed into high resolution radar images by software on the CYBER computer
Neotectonics of the San Andreas fault system: Basin and range province juncture
Several new details regarding the surficial patterns of neotectonic activity of the Eastern Transverse Ranges and vicinity were discovered. Additionally a number of data display and analysis techniques were developed. These findings will be useful both in the continued development of neotectonic models for southern California and for the future application of remote sensing methodologies elsewhere
Neotectonics of the San Andreas Fault system, basin and range province juncture
The development, active processes, and tectonic interplay of the southern San Andreas fault system and the basin and range province were studied. The study consist of data acquisition and evaluation, technique development, and image interpretation and mapping. Potentially significant geologic findings are discussed
Diversity, Inclusion and the ExCEEd Teaching Workshop
The American Society of Civil Engineers (ASCE) Excellence in Civil Engineering Education (ExCEEd) Teaching Workshops are currently in their 20th year of existence and have been highly successful. There is a growing body of literature on creating a multi-cultural classroom that celebrates diversity, accounts for the global differences and experiences of students, and deliberately fosters inclusivity. This paper examines the content of the existing culturally inclusive literature and quantifies how much is already present in the current ETW curriculum. It then suggests how much more could be included if a deliberate effort is made to include diversity and inclusivity into the workshop content. It suggests what elements in the culturally inclusive literature are not feasible to include in a one-week workshop. Finally, it makes recommendations on how to best revise the current ETW to include and incorporate this content without lengthening the time of the workshop
