Abstract: In a monopulse radar system the phase difference between successive echoes from the same target is modified to make this difference equal to what it would be if the target were on the axis of the beam.

Abstract: In order to narrow the bandwidth of a communication channel through which electrical signals are to be transmitted the latter are passed through an electro-optical device comprising doublediffraction optical system employing monochromatic light. The double-diffraction system is equipped with an electro-optical modulator to which the electrical signals are applied and a photoelectric transducer collects the spatially modulated monochromatic light after filtering therefrom of certain spectrum components, the remaining spectrum components having been juxtaposed.

Abstract: To provide for digital positioning, without inertia of moving parts, a laser beam is transmitted to a substrate which is to be exposed, etched, or the like, particularly when microcircuits are to be produced, by monitoring the displacement of the substrate, mechanically, in two mutually perpendicular directions and positioning the laser beam, as monitored, in at least one direction by controlling voltages applied to a deflector cell in the path of the laser beam, by digitally, selectively, energizing an electro optical crystal effective to rotate the polarized laser beam through a plane of 90*, followed by a doubly refracting crystal which deviates the path of the laser beam, depending on its direction of polarization with respect to the optical axis of the crystal, so that, by successive deflections, the beam, from the laser, can be positioned in predetermined locations on the substrate. The entire arrangement is preferably computer controlled, so that data inserted into the computer will cause deflection of the laser beam in accordance with a predetermined program.

Abstract: An improvement in hetrodyne-type microwave radiometers, comprising a polarization changer for passing, with crossed polarizations, the signals respectively coming from a radio source and a reference source, a first rotator, such as of the Faraday type, operated at low frequency, an mode suppressor and a mixer connected to a local oscillator, wherein a second rotator, such as of the Faraday type producing a constant rotation in the polarization, is arranged between the mode suppressor and said mixer.

Abstract: A triggered pulse generator comprising a load inductor, controlled discharging means and pulse shaping means; the load inductor builds up the secondary winding of a transformer whose primary winding is fed with a sawtooth voltage synchronized with the discharging means control. The voltage of the triggered pulse may be controlled through controlling the duration of the teeth of the sawtooth voltage.
