Abstract: In a method for the flight control of a plurality of aircraft flying in formation with respect to one another, correction signals are generated for an autopilot system or a command display in order to allow one or more following aircraft within the formation to follow a lead aircraft in the formation in a predeterminable relative position. A nominal trajectory of the following aircraft, parallel to the trajectory (1) of the lead aircraft, is calculated at each instantaneous position P?act of the following aircraft, which trajectory runs through the instantaneous actual position P?act and a reference point P?RP. (The reference point P?RP is the projection of a point PRP, which is separated by the longitudinal nominal distance xnom between the lead aircraft and the following aircraft, on the trajectory of the lead aircraft, taking into account the lateral and vertical actual distances yact and zact between the trajectory of the lead aircraft and that of the following aircraft.

Abstract: Disclosed is a new alternative method for the phase unwrapping of the interferogram of two SAR (Synthetic Aperture Radar) images of the same area. This new method uses an iterative approach to the phase unwrapping problem by applying local circular or elliptical masks centered on the phase residues. A phase unwrapping error is detected automatically during the unwrapping process by comparing each unwrapped value with neighboring unwrapped values. This new method for phase unwrapping significantly improves the quality of unwrapped phase maps. This will allow extraction of quantitative information such as height and deformation from interferometric SAR measurements. This is significant for the routine application of SAR interferometry in fields like digital elevation mapping and large scale deformation mapping.
