    AMPLIFIER DEVICE FOR RADAR ANTENNAS
    The present invention radar. bereferyetamplifier device for antennas
    s 10 More specifically, the invention provides a pyramidal amplifier device for radar antennas specially adapted for topology of M3 dual-horn antennas of the type that include Fresnel lenses, which allows to first focus or concentrate the signal for these large aperture applications. and, secondly, to facilitate the operation of the antenna in both vertical and horizontal polarization.
    fifteen Thus, the pyramidal amplifying device manages to significantly increase the capture capacity of a radar antenna and achieve lower polarity discrimination, in addition to presenting various improvements that substantially improve its performance and effectiveness, being particularly adapted for topology of dual M3 antennas. horn, for example of the Escort® and Beltornics® type.
    twenty Within the scope of the practical application of the invention it is known that current radar signal detecting systems, between frequencies (33, 392 and 35,998) Y (24, 000 and 24, 350) GHz, do not always have an adequate gain that allows its detection reliably and at a sufficient distance from the emitting focus.
    In addition, new technological advances in the field of radar detection have applied the technology of Fresnel lenses, which allow a polarization of vertical to horizontal waves, so they detect with the same distance the radars that emit in horizontal polarization and those that They do it vertically.
    25 The present invention allows to implement these new topology of dual horn antennas that include Fresnel lenses by providing an amplifying device for radar antennas of the aforementioned type that allows improving the
    For this, the amplifier device for radar antennas is constituted by a
    first amplifying element (1) hollow trunk-pyramidal shape whose base
    5 is available to the outside environment in order to facilitate collection, and
    which allows to improve the receiver capacities in the bandwidth
    mentioned regarding the detection of radar signals. This first
    amplifier element (1) is supported by way of fitting into a second support element (7) where the amplifier element is assembled, engaging in
    10 inside the antenna part that includes one of the Fresnel lenses.
    The invention is described below on the basis of an embodiment thereof and with reference to the attached figures, in which:
    Fig. 1: Plan view of the amplifier element a) showing the upper part; b) showing the lateral part;
    15 Fig. 2: Perspective view of the amplifier element of Fig. 1:
    Fig. 3: Perspective view of the support element;
    Fig. 4: Shows the coupling between the amplifier and support elements
    in an open state;
    Fig. 5: Shows the device in assembled state coupled to a 20-horn radar antenna incorporating two Fresnel lenses.
    Referring to Fig. 1, the amplifier element (1) is made up of two
    symmetric bases (2), of which only one is shown in Fig. 1a) for simplicity, and by two equally symmetrical sides (3) and of which only of
    shows one in Fig. 1) for the same reasons.
    25 As can be seen in Fig. 1, the symmetric bases (2) constitute two opposite faces of the trunk-pyramidal amplifying element, of rectangular base, and
    symmetrical sides (3) constitute opposite lateral faces of the rectangular base element by means of a set of tabs (4) and grooves (4 ') located
    correspondingly at the edges of the bases (2) and the sides (3), which
    It allows quick assembly without the need for tools of the amplifier element.
    As seen in Figs. 1a and 2, the symmetric bases (2) are shaped
    essentially of isosceles trapezoid, whose obtuse internal angles are 1000
    and present, in correspondence with the minor base (5) of the trapezoid, a recess
    central circular forming a perimeter convex edge (6) whose rope to the
    lower base level is substantially shorter than the length of said lower base (5).
    On the other hand, the symmetrical sides (3) also have an isosceles trapezoid shape, with an acute interior angle of 80 °, as shown in Fig. 1b).
    The amplifier element (1), once mounted, adopts the trunk-pyramidal shape
    indicated, adapting its size to the wavelengths according to
    those corresponding to the radar antenna, as is known in the art.
    Referring now to Fig. 3, the support element (7) is constituted by a hollow straight parallelepiped open by one of its faces, these being
    sized in correspondence with the size of the radar antenna to be housed
    partially. As seen in the figure, the opposite side of the open
    support element (7) has a recess or window (8) forming a step of
    light for the two Fresnel lenses present in the antenna and to be housed in the support element (7), therefore the window (8) being sized in correspondence
    with the size of these lenses. The rest of the faces (Fig. 4), continuous and without windows, constitute corresponding covers (9) of the support element (7),
    covering the Fresnel lenses of the antenna as well as part of the element
    amplifier (1), being practicable for access to the radar antenna.
    As seen in Fig. 4, the amplifier element (1) is arranged by its
    convex zone in the window (8) of the support (2) in correspondence with one of the Exterior.
    Although in this embodiment the support element has a configuration
    parallelepipedic, it could adopt other different configurations, provided that in 5 the part corresponding to the coupling of the Fresnel lenses maintains the described configuration and is sized to accommodate the components
    indicated.
