Abstract: An image conversion method is provided for integrating a security feature in a digital source image to generate a target image secured by the integrated security feature. The image conversion method includes carrying out transverse-wave-shaped distortion of the source image to generate an intermediate image; generating a target image, the intermediate image being scanned by rows of pixels to define, per row of pixels of the intermediate image, a sequence of successive pixels according to the scanning, and each pixel of the sequence being transformed to a corresponding pixel of the target image. The arrangement of the respective pixels of each sequence is a transverse-wave-shaped wave packet in the target image; and the integrated security feature is defined by the wave packets.

An identification card comprising a colour image is shown.

Abstract: A RF antenna system mounted on, for example, a dielectric carrier plate is accommodated as a homing head in the front under a radome in a missile provided for locating radar systems or the like, in addition to other, further sensors potentially present in free spaces. The RF antenna system is composed of a three's or four's group of logarithmic-periodic crossed dipole antennas whose long axes proceed with optimized dimension obliquely relative to one another and that are interconnected with a monopulse feed network for taking aggregate and difference diagrams in azimuth and elevation. The antenna system for long-range missiles enables a monopulse position fixing in azimuthal or, respectively, elevational direction in an extremely broad frequency range.

Abstract: A secondary radar transponder on a mobile target has an antenna arrangement which can receive interrogation signals from all directions and radiate reply signals. The antenna arrangement includes several individual antennas, each of which, with its primary lobe, covers a specific sector of the entire 360.degree. range and is connected to a receiver, so that through receiving level comparison, that particular sector from which the interrogation signal incides can be ascertained. The reply signal is then radiated only by the individual antenna covering that particular sector. The transponder is particularly suited for identification friend-foe (IFF) purposes.

Abstract: This invention relates to an antenna system for a jamming transmitter which is intended to protect a remote object which is remote from the jamming transmitter as well as itself or an object in the immediate vicinity of the jamming transmitter. Known jammer antennas for this purpose radiate either a pencil beam which presents considerable problems in the alignment and orientation and tracking in two planes or alternatively such known antennas are designed as omni directional antenna which however have low antenna gain and are easily detected. In the present invention the difficulties of the prior art are eliminated in that a separate antenna is provided for external or foreign protection and a separate antenna for self protection which antennas produced in the first plane a sharply focused pattern and in a plane perpendicular thereto a radiation pattern (7, 8) which is optimized for external or foreign protection or self protection, respectively.

Additionally, orthogonal polarization suppression is achieved with the apparatus of the invention. The invention can be applied to a radom of a target tracking radar antenna, for example.
