摘要：
The invention relates to a method and to an apparatus for determining a displacement vector field (90) of a scenario (9), by a ground-based interferometric radar system operated in multi-bistatic mode and comprising a main radar transceiver device (10) and at least one passive radar receiver device (20) arranged at a predetermined distance from each other, in which the oscillators (11,21) of the at least two radar are synchronized, in time and in frequency, in particular according to a signal coming from a global positioning system (100). The method provides a step of interferometrically determining (5) at least one first displacement map (77) and one second displacement map (78) of the scenario (9) between a previous time (t') and a subsequent time (t"), expressed in a global reference system and having each a plurality of pixels each associated to a respective domain (8) of the scenario (9). The first and the second displacement maps (77,78) comprise first and second displacement components (41) of the pixe
