Inventor: VOITENKO OLEKSANDR HRYHOROVYCH
Filed: 1999-10-19
Abstract: The proposed output band-pass filter for a microwave transmitter can be used in television, radio link, radar, and other transmitting and receiving microwave systems. The proposed output band-pass filter of a microwave transmitter with an evanescent-mode waveguide, which contains at least two dielectric resonators installed on insulating pads, and an input coupling pin that is used as an input of the filter and installed near the first dielectric resonator, differs in that the casing of the evanescent-mode waveguide has, on the output side, a widening with linear dimensions corresponding to those of the transmitting channel waveguide. This widening is hermetically sealed with dielectric gasket. The dielectric resonators together with the insulating pads are arranged so that the last dielectric resonator is positioned at the boundary line of the evanescent-mode waveguide widening. Within the whole width of the evanescent-mode waveguide, over the last dielectric resonator, an output coupling comb element is formed. The coupling comb element dimensions not exceed /8, where is a wavelength. The proposed structure allows a possibility to seal the filter, reduce loss of an effective signal at the filter output, simplify changeover from microstrip to waveguide structures, simplify the construction, reduce the overall dimensions, and enhance stability of the filter characteristics in operation.

Abstract: FIELD: underwater acoustics associated with reception of wide-band signals, applicable in hydrophoning, sonar direction finding, detection of hydroacoustic signals, classifying, underwater communication, for underwater geophysical operations. SUBSTANCE: two modifications of the method are claimed. According to the first modification of the method, which includes the reception of signal from the direction of the main maximum of the directional pattern of the multiwire equidistant antenna, the signals are received within frequency band   where c - sound velocity, d - distance between the wires, θ-current angle, θ 0 -compensation angle. Within this frequency band one more or several maxima symmetrically positioned relative to the main additional maximum are formed in the directional pattern. The reception frequency is changed up to variation of the angular distances between the main and each of the additional maxima by an angle not less than the angular width of the additional maximum in a level of 3 dB. If the signal is received, the direction of signal input is determined as the direction of the additional maximum. For defining more exactly the direction in the presence of two additional maxima at the varied frequency of reception the directional pattern is turned until one of the additional maxima coincides with the initial one. At fixing of the signal this direction is determined as the direction of signal input from the source, and in its absence - as the direction of the other additional maximum at the initial frequency of reception. According to the second modification of the method, reception is accomplished simultaneously at two different frequencies f a , f b , in this case each of frequencies f a , f b  satisfies condition (1). If the signal is received at both frequencies, the direction of signal input is determined as the direction of the main maximum, if at one of the frequencies - as the direction of the additional maximum at the given first frequency. For defining more exactly the direction in the presence of two additional maxima the directional pattern is turned at the second frequency until one of the additional maxima coincides with the direction of the additional maximum at the first frequency, where the signal is received. At the reception of the signal at the second frequency this direction is determined as the direction of signal input from the source, and in the absence - as the direction of the other additional maximum at the first frequency. EFFECT: expanded frequency band in the range of which the direction to the signal source is determined unambiguously at similar wave dimensions between the antenna wires, enhanced accuracy of direction finding, reduced number of active antenna wires, quantity of channels, cost at the same wave dimension of the antenna. 2 cl, 4 dwg
