    Adaptive antenna arrays are aerial arrays which are able to adjust themselves automatically and electronically to meet particular constraints. In this paper, arrays in which the reception of interfering signals is minimised are considered. The theory of a particular form of these arrays, the linear uniformly spaced array of identical elements, is introduced and some of the possible adaptation algo... View full abstract»

    Adaptive arrays are aerial arrays which are able to adjust themselves automatically and electronically to meet particular constraints. The IBA's steerable adaptive broadcast equipment (s.a.b.r.e.) is designed for the reception of u.h.f. television signals where the constraint is that of minimising the level of cochannel interference relative to the wanted signal. The paper describes the first prac... View full abstract»

    Current generation sonar systems employ high temporal and spatial resolution to achieve acceptable operational performance. This, together with the physical mechanisms of acoustic propagation in the ocean, places a number of constraints on the implementation of beam-forming systems for sonar applications that are in many ways unique; in particular: (a) Low sonar operating frequencies and the use o...

    Development of digital methods for antenna beam forming in the receiving mode of a radar can be advantageous in providing the system with a high degree of flexibility in `beam-pattern management¿ for countering e.c.m. and providing multiple functions efficiently. The justification for incorporating digital methods and various possible arrangements are discussed first. The main body of the paper i... View full abstract»

    A description of the ELRA phased array radar at FFM in Germany is given. This phased array, comprising separate active transmitting and receiving antennas, acts as a test bed for a wide variety of radar waveforms and signal-processing techniques. Emphasis is placed in the present paper on a description of the array hardware and the test or adjustment procedures used to achieve the desired radiatio... View full abstract»

    A review of microwave devices for power generation and low-noise amplification in active array modules is given. Various configurations of active array module are discussed and particularly full attention is given to the use of microwave phase-locked loops to achieve the required gain and accurate phase control. The noise performance and response to pulse-compression waveforms for such loops is al... View full abstract»

    The use of gallium arsenide as a material for monolithic microwave circuits where active devices, such as f.e.t.s, diodes etc., are integrated onto the same piece of material as passive components is now receiving considerable attention in Europe and the USA. The paper concentrates on the specific role of monolithic circuits in phased-array-radar applications with descriptions of the use of f.e.t.... View full abstract»

    Use of multiple active devices in phased-array radars to generate r.f. power is becoming more interesting, owing to the technical advantages of solid-state components. Because the solid-state components have peak-power limitations instead of the mean-power limitations of traditional components, it is more cost effective to transmit signals with a high duty factor. Furthermore, one of the most impo... View full abstract»

    A technique for cancer treatment using focused microwave arrays to induce hyperthermia is developed. The system as initially proposed consists of orthogonal linear-phased arrays whose focusing properties are allied to the weakness of malignant cells to excessive heat. A two-dimensional computer simulation of the power dissipation inside a cylindrical body, with uniform permittivity and attenuation... View full abstract»

    Seismic energy can be coupled into a coal seam waveguide from an underground explosion. Guided modes scattered by buried faults may illuminate an underground geophone array. The fault mapping procedures that form the subject of this paper are based on coherent digital recording of signals sensed by the elements of such an array. The inverse scattering problem tackled is unusual. Coal seams are dis... View full abstract»
