This paper shows that the coherent interferometric imaging strategy originally proposed in the context of passive or active arrays of antennas can be implemented for synthetic aperture radar, in which a single antenna is used as an emitter and as a receiver at successive positions along a trajectory. The idea is to backpropagate the cross correlations of the recorded signals over selected frequ...

Flooding is one of the most devastating natural disasters occurring annually in the Philippines. A call for a solution for this malady is very challenging as well as crucial to be addressed. Mapping flood hazard is an effective tool in determining the extent and depth of floods associated with hazard level in specified areas that need to be prioritized during flood occurrences. Precedent to the...

During the last two decades synthetic aperture radar (SAR) and interferometric synthetic aperture radar (InSAR) have become important tools for airborne and satellite remote sensing. SAR delivers a high resolution image of the radar backscatter and by means of InSAR a second image from almost the same orbit is combined with the first one to provide the relative phase difference and stability/co...

Interpolation is required in interferometric synthetic aperture radar (SAR) processing for coregistration of complex signals. Straightforward system theoretical considerations provide objective figures of merit for interpolators, such as interferometric decorrelation and phase noise. Theoretical and simulation results are given for nearest neighbor, piecewise linear, fourand six-point cubic con...

In the last two decades, scientists have developed a powerful technique to measure the millimeterscale of the Earth ̳s surface deformation by comparing complex synthetic aperture radar (SAR) data that were acquired a few days or a few years apart. This technique is known as interferometric synthetic aperture radar (InSAR). The paper is focused on simulation of volume deformation of coastal éros...
