Considerations of the Orbital Tube for Interferometric Applications
نویسندگان
چکیده
Current spaceborne SAR missions steer the satellite to follow an orbital tube in order to guarantee interferometric compatibility between data takes. In this contribution it is shown that the size of the orbital tube can impact the interferometric performance in terms of azimuth spectral decorrelation and azimuth coregistration requirements under high Doppler centroids, which can be specially critical in burst modes, namely, ScanSAR and TOPS. The paper presents and analyses these aspects in the frame of the Sentinel-1 mission.

In this paper the earth’s magnetic field is simulated precisely while the intensity and direction of the field are verified with one of the standard references for selected points on the earth and the results are compared with some low-order models. In another simulation, the complete model is compared with a common approximate model. The magnetic field in orbital frame is described and to empl...

متن کاملNew geometry for TCP: severe plastic deformation of tubes
Since tubes are widely used for different industrial applications, processing of tubes by the Severe Plastic Deformation (SPD) method has been the target of different attempts. Among these attempts, development of SPD processes for tubes based on Equal Channel Angular Pressing (ECAP) has been more successful. As an illustration, Tube Channel Pressing (TCP) has been presented as an attractive SP...
متن کاملOptimization of die geometry for Tube Channel Pressing
Since tubes have numerous industrial applications, different attempts are focused on the Severe Plastic Deformation (SPD) processes of tubes. As an illustration, Tube Channel Pressing (TCP) is an attractive process for this purpose since it can be used for processing of different sizes of tubes. However, more attempts are needed to improve the outcomes of TCP. For example, imposing of greater s...
