Mom who Maps

I have just attended an InSAR training  showing how to detect surface deformation through phase differences between SAR signals. SAR satellite transmits microwave to earth and receives reflected microwave signals from earth surface. The intensity of received microwave indicates electromagnetic characteristics of objects, and phase indicates distance between aperture and object. Surface deformation is measured by the difference in two observed phases. The observed phase differences still contains errors that ought to be corrected along processing enumerated by the steps below. Getting SLC (Single-Look Complex) Co-registration (registration of Master and Slave images) Interferometry ( measuring phase differences) Corrections (Removal of Orbital and Topographic Fringe) Phase Unwrapping (integration of extracted to actual phase difference) Geocoding Visualization of Results in ENVI Analysis and Interpretation With the use of ALOS Palsar images from two different instances ...

 Being part of the GPS Team in our office, we are tasked to map the crustal deformation along the Philippine Fault as well as other tectonically active locations in the Philippines using Differential GPS. Apart from GPS , there are other means of quantifying such deformation, one is through remote sensing with the use of satellite images. RADAR is a means to remotely sense and analyse an environment such as the Earth. I have just been part of a RADAR training, specifically inSAR (Interferometric Synthetic Aperture Radar) that was held in the Philippine Institute of Volcanology and Seismology (PHIVOLCS) Auditorium held last September 5-6. This technical training was brought to us by JAXA - Sentinel Asia. It was an engaging experience and I surely learned a lot. Will have a separate post for that later. I am looking forward to applying the principles in the current research projects that I am in.
