Title: Motion compensation in synthetic aperture radar
Inventor: ELLIS ALFRED BRIAN EDWIN
IPC: G01S13/90
Filed: 1992-08-25
Abstract: In a synthetic aperture radar (S.A.R) system distortion caused by lateral movement of the synthetic aperture radar platform can be removed by taking the radar samples for a number of range cells scattered across the swath and dividing them into odd and even samples. The odd and even samples are then separately processed as in a conventional synthetic aperture radar using a filter matched to the expected movements of the platform to generate complex vectors and the phase difference between these vectors is measured. The average phase difference across the range cells can be used to deduce the actual movement of the aircraft or modify the matched filter in an iterative approach. <IMAGE>

Title: Image enhancement device
Inventor: NEWTON ANTHONY DAVID
IPC: H01J31/56
Filed: 1992-12-24
Abstract: An image enhancement device 10 in which light emitted from a source 8 passes through a set of colour filters 21, 31, 41 and falls upon a set of photocathodes 22. Electrons emitted by the photocathodes are accelerated by an electric field before impacting a set of phosphors 23. Light generated by the phosphors then falls upon a further set of photocathodes 24. The process is then repeated until the enhanced image 9 is emitted by the final set of phosphors 27. The filters may chosen such that the first and final images have the same colour characteristic. Alternatively, if the first image is a photographic colour negative, the filters are chosen such that the final image has normal colour. <IMAGE>

Title: Comparing geological samples
Inventor: ST LUM HANS-HENRIK
IPC: G01N33/24
Filed: 1993-10-19
Abstract: A method of comparing at least two geological samples comprises obtaining for each of the samples a set of values of an isotope ratio for a plurality of positions in each of the samples, comparing the clustering of the values in the respective sets of values, and therefrom inferring information concerning the degree of similarity of the samples. Typically, the comparing of the clustering is done by analysing each set of isotope ratio values to identify one or more clusters of values in each set and then comparing a cluster or clusters in one set with a cluster or clusters in another set to identify significant differences or similarities of the clusters. This may be done while ignoring differences in absolute values of the members of the clusters. Suitably the comparison is done using a statistical analysis technique. Isotope ratio may be that of two strontium isotopes.
