Filed: 1963-10-14
Abstract: 1,003,409. Aerials; pulse radar. GENERAL PRECISION Inc. Oct. 14, 1963 [Dec. 6, 1962], No. 40505/63. Headings H4A and H4D. An antenna for use with pulse Doppler navigation systems in aircraft consists of a pair of rectangular waveguides 20 and 40 mounted alongside one another, each having a series of resonant longitudinal shunt slots 21-28 and 41-48 respectively formed on their broad faces, and first 54 and second 55 planar conductive reflectors positioned adjacent the outermost sides of the waveguides and angled from a plane normal to the surfaces of the broad faces of the waveguide (Fig. 4, not shown). The slots of each waveguide are all formed on the same side of the centre line 31 and 52 of their respective waveguide but at varying distances therefrom so that a line drawn through their centres would bow away from the longitudinal axis 53 of the antenna as shown in Fig. 3, the arrangement being such as to produce tapered or gable illumination with a power taper of 4: 1. The waveguides 20 and 40 are staggered longitudinally of each other so that the slots 41-48 in the waveguide 40 lie opposite the spaces between the slots 21-28 in the waveguide 20. The antenna radiates a pair of beams 13, 16 or 14, 15, Fig. 1, which intersect the surface of the ground along hyperbolic lines of constant Doppler frequency (isodops), each beam being wide in the direction along an isodop so that in a system in which the receiver is blocked during pulse transmission echo signals due to the side portions, e.g. side lobes, of the beam are still passed by the receiver even at very low altitudes, thereby allowing reliable operation down to ground level. The waveguides 20 and 40 are fed from opposite ends through 90 degree bends, the ends opposite to the feed ends being closed with shorting plates 51 and 34. The phase of the energy fed to the two arrays is such that in one mode of operation the slots 21 and 41 receive energy of the same phase thereby generating one pair of beams 13 and 16. To produce the beams 14, 15 the phase of the energy fed to one of the waveguides is periodically reversed so that in this mode, slots 21 and 41 receive energy with a phase difference of 180 degrees. The dimensions of the aerial for use at different frequencies are given.
