A process for optimizing the operation of an active lateral-view sensor when the height above the surface to be detected is variable, includes the following steps: i) continuously determining the height of the lateral-view sensor above the surface to be detected, and ii) adjusting the scanning beams emitted by the lateral-view sensor for scanning the surface to be detected by roll rotation as a function of the determined height of the lateral-view sensor such that variation of the surface to be detected is reduced during the orbit of the lateral-view sensor.

Method for optimizing the operation of an active lateral-view sensor when the height above the surface to be detected is variable

In a method for interferometric radar measurement, at least two side looking RADAR systems on satellite and/or missile-supported platforms illuminate a common surface area by means of microwave signals. A first side looking RADAR system sends a first radar signal on a first transmit frequency, and at least a second side looking RADAR system sends at least a second radar signal on at least a second transmit frequency. At least one of the at least two side looking RADAR systems receives the at least two interfering radar signals reflected on the common surface area, determines difference phases of the received radar signals from the interferograms, determines therefrom a drift of a system clock of the at least two side looking RADAR systems, and compensates the determined drift.

Method and apparatus for interferometric radar measurement

A method of radar measurement by transmitting and receiving radar signals with at least two spatially separated radar systems. The method further includes exchanging reference radar signals between the at least two radar systems to determine measurement-relevant parameters. Moreover, a determination of at least one of a relative phase relationship of the reference radar signals of the radar systems and a relative time position of time references of the radar systems is based on reference radar signals received. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
