Abstract: In order to enable intermittent output of an oscillation signal without essentially producing a leak in response to a pulse signal indicating a transmission timing of a radar wave, a radar oscillator is provided which employs a configuration in which an operation of an oscillating unit itself is alternately changed between an oscillating state and an oscillation stop state by a switch, rather than a configuration in which an output passage of an oscillation signal is switched to be opened and closed as in a conventional radar oscillator.

Abstract: A new method for transmitter-receiver design that enhances the desired signal output from the receiver while minimizing the total interference and noise output from the receiver at the desired decision making instant is presented. Further the new design scheme proposed here can be used for transmit signal energy and bandwidth tradeoff. As a result, transmit signal energy can be used to tradeoff for the “premium” signal bandwidth without sacrificing the system performance level in terms of the output Signal to Interference plus Noise power Ratio (SINR). The two designs—the one before and the one after the tradeoff—will result in two different transmitter-receiver pairs that have the same performance level. In many applications such as in telecommunications, since the available bandwidth is at premium, such a tradeoff will result in releasing otherwise unavailable bandwidth at the expense of additional signal energy. The bandwidth so released can be used for other applications or to add additional telecommunication capacity to the system.

Abstract: The portion corresponding to a main bang signal leaking from a transmission/reception switching unit is extracted as a frequency estimation signal from an IF signal from a mixer in a signal extracting unit, a frequency is estimated in a frequency estimating unit, and the frequency of a local oscillation signal of a local oscillator is controlled so that the frequency of the IF signal is equal to a target value. The frequency estimation in the frequency estimating unit is carried out by using Discrete Fourier Transform or Fast Fourier Transform.

Abstract: An illumination source of predominantly non-directional and incoherent millimeter-wave radiation for illuminating an area for passive millimeter-wave imaging comprises a container with at least a partly reflective internal surface and a plurality of exit apertures and a primary source of millimeter-wave radiation for emitting millimeter-wave radiation into the container. The primary source and the container are arranged so that a proportion of the millimeter-wave radiation emitted by the source undergoes reflection within the container before being emitted through the apertures, such that the different paths lengths are at least equal to the coherence length of the radiation. This is facilitated if the bandwidth of the radiation is preferably at least 1 GHz. The container may be a box in which a waveguide is used to couple radiation from the primary source into the box. Alternatively, the container may be formed from a mesh and the plurality of holes is provided by the holes in the mesh.

Abstract: In a radar sensor, a continuous microwave signal is passed through an RF switch which is periodically controlled by a pulse signal. The pulse signal is frequency modulated in such a way that the spectrum of the pulse signal is expanded without decorrelation occurring. Using this arrangement, the noise level is kept low and the detection range is increased.

Abstract: An improved millimetre wave illumination system includes at least one primary source of millimetre wave radiation, a reflecting surface and a baffle comprising a plurality of exit apertures arranged such that at least some of the radiation from the source is reflected from the reflective surface before proceeding to the baffle, characterised in that means are incorporated for generating a plurality of radiation field states within a pre-determined time interval. The baffle, source and reflector are preferably packaged into a container with the exit apertures providing an illumination output. The generation of the plurality of radiation field states provides an illumination at the illuminator output that is less spatially variable when integrated over the pre-determined time interval. Embodiments of the invention show means for generating the plurality of radiation field states including relative movement of the reflective surface, variable positioning of the source with respect to the reflective surface, and including multiple sources within a single system.
