Title: Conjugate emission of coherent light and energy-charged material particles, and device for implementing such an emission
IPC: H05H3/02
Filed: 1983-11-30
Abstract: Conjugate emission of coherent light and energy-charged particles, and device for implementing such an emission: a. In order to implement the invention, use is made of the resonant cavity, an irradiated system consisting of two parallel walls, a mirror, and a semi-transparent mirror, emitting a beam of coherent light: hv (laser); b. Forming part of the invention, a permanently irradiated device, branched from the resonant cavity, in which the semi-transparent mirror is replaced by a grid with very low optical transparency, and fed continuously with absorbent particles A + hv T A DEG c. Conjugate emission is realised, by combining the devices a and b, in such a way that the charged particles A DEG ejected through the pores of the grid remain contained, during their journey to the chosen target, within the beam of coherent light: hv. The invention can be used in various fields, in particular in medicine and biology.
Patent FR-2732469-A1 (FR)
Title: Radar jammer searching and position detecting method
Inventor: CHEKROUN CLAUDE
IPC: G01S7/36
Filed: 1984-01-23
Abstract: The method involves using a filter placed in front of the radar antenna. The filter includes an array of conductive wires carrying diodes. Modulation of the currents in the wires allows to obtain a modulation in response to the amplitude of the secondary lobes of the antenna radiation diaphragm. The modulation is done in such a way that an over-current zone or "peak" is moved by increasing the level of a secondary lobe, angularly spaced from the antenna pointing direction, by 10 or 15 decibels.  The angle value between the secondary lobes and the pointing direction is continuously determined. This value is function of the currents modulation applied to the array. The noise level received by the antenna is also continuously detected for each angle value. The jammer direction is evaluated from the maximum received noise levels.
