ABSTRACT:
A radiation detection method utilizing essentially two serial arrangements of receiving elements which are rigidly connected to a reconnaissance plane (1) and of different lengths, which yield in longitudinal direction of sight the censor angle .epsilon. and on the ground the pictorial strips (6, 6'). The pictorial strips are arranged transverse to the axis (25) of the plane and parallel to each other. The processing of the signals is such that, by scanning the two serial arrangements with a time delay, a different signal signature results only if the scanned object (2) moves during over flight, independently of whether the reconnaissance plane (1) during the measuring operation is subject to a pitch angle .alpha. and/or a side slip angle .beta. and/or a roll angle speed. Moreover, in this way, it is also possible to independently obtain the target speed and direction.
