Abstract: The method involves using multiple aperture multiplexing, with display of image composite in fast sequences such that viewer does not detect changes. The method involves using a screen and an optical closure device in the beam path that can be blocked or made transparent for the segment. The observer is positioned within a defined distance and angular range with respect to the associated device. Perspective views are acquired in real time or non-real time using one or more or one moving image acquisition devices. This provides digital data sets that are converted into suitable image composites and displayed on a screen by a multiplex method. A controller opens one or more closure device apertures to display the image composite, in a sequence so fast that the observer does not detect the changes.

Abstract: In a method for resolving ambiguity in the determination of antenna angle of view and Doppler frequency in synthetic aperture radar (SAR), by evaluating the dependence of the Doppler frequency on the transmitting frequency a skew of the two-dimensional Fourier power spectrum or the two-dimensional autocorrelation function of radar data is measured in that the radar data are subjected to a range Fourier transformation and for the individual range frequencies in a following Doppler centroid estimator a Doppler centroid determination is carried out in the azimuth direction.By this method the pulse repetition frequency ambiguities are eliminated without any demands having to be made on the data acquisition or a high image contrast; this method can therefore be applied to any region of the raw data matrix. Moreover, no azimuth compression is necessary.

Abstract: In a method for correcting range migration in image generation in synthetic aperture radar (SAR) to eliminate the entire range migration or the residual range migration left by a conventional focussing method, prior to the range compression the data are transformed to the range-Doppler domain and there multiplied by a specific two-dimensional phase function; after an additional range Fourier transformatioin the range compression is then carried out with a specifically modified range transfer function and thereafter a range inverse Fourier transformation performed. Furthermore, a corresponding residual phase error is corrected. In addition, the data can if necessary be segmented in range or a range precompression performed.With the method according to the invention the range migration is completely eliminated without having to perform an explicit interpolation.
