Abstract: This target detection polarimetrical processing circuit comprises, in parallel, a polarimetrical CFAR detector provided with a target detection output, a polarimetrical clutter-rejection filter associated with a CFAR detector provided with a target detection output and a bank of polarimetrical filters associated with CFAR detectors provided with target detection outputs, and an "OR" type logic circuit combining the different target detection outputs and a selection circuit activating the polarimetrical clutter-rejection filter and disabling the bank of polarimetrical filters when the degree of polarization of the clutter exceeds a certain threshold and conversely disabling the polarimetrical clutter-rejection filter and activating the bank of polarimetrical filters when the degree of polarization of the clutter is below said threshold.

Abstract: The invention relates to a method for producing a cylindrical body comprising at least one stud having a cylindrical base portion projecting from its rotating surface in which a cylindrical body blank is produced comprising a peripheral collar of external diameter equal to that of the stud or studs to be obtained, and of width greater than the diameter of the base of the stud or studs to be obtained.

Abstract: The invention relates to a process and an installation for the treatment of tritium-contaminated, solid organic waste. The waste is contacted with the steam in enclosure (1) for extracting the tritium in the steam and the steam is then condensed at (11 and 13) to recover the tritium from the waste in the form of tritiated water.

Abstract: A microwave primary source with a phase conical scan having a conical horn containing an obstacle which gives rise to a wave that propagates in the TE.sub.21 mode in quadrature with the TE.sub.11 fundamental mode in the opening of the horn; the obstacle is driven in rotation round the axis V of the horn.

Abstract: A device for exciting a corrugated ultra-high frequency source of revolution operating in two remote frequency bands, decoupled mechanically from the source. The device includes two excitation devices corresponding to the two operating bands, placed perpendicularly to each other, at respective distances from the mouth of the source such that the waves which they emit remain canalized in the Rayleigh zone of each device and provide optimum coupling between these device and the source.
