PCT No. PCT/DE96/00534 Sec. 371 Date Sep. 22, 1997 Sec. 102(e) Date Sep. 22, 1997 PCT Filed Mar. 27, 1996 PCT Pub. No. WO96/30777 PCT Pub. Date Oct. 3, 1996A method is specified for the high-resolution evaluation and, if appropriate, for the recovery of narrow-band signals, received by a centrosymmetrical sensor group (AG), for directional estimation. A method is also specified for the high-resolution evaluation of superimposed non-attenuated harmonic signals for spectral analysis in the case, if appropriate, of multi-channel observations. For directional estimation, signals which are noisy and disturbed by multipath propagation can be prepared for recovery. The method for directional estimation is particularly suitable for signal evaluation in mobile radio systems or wireless communication systems, in high-resolution radar image processing systems, sonar systems, and medical technology systems. The method for frequency estimation is suitable for image processing applications, and for a multiplicity of spectral analysis applications.
