Filed: 1946-09-11
Abstract: 628,981. Radiolocation. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Sept. 11, 1946, No. 27340. Convention date, Dec. 6, 1939. [Class 40 (vii)] The transmission and reception characteristics of a directional pulse radar system are of elongated shape in cross-section and are caused to rotate about their mean axes, whereby searching is facilitated on account of the extent of the larger dimension of the beam sections, and whereby a target may be accurately located by training the axis of rotation upon it, as indicated by the reception of a continuous echo signal. The transmitting or receiving aerial, Fig. 4, comprising a dipole A and paraboloidal reflector R, has a narrow directional characteristic in the plane indicated by X, X<1> since the dipole acts as an omnidirectional point source in that plane and has a broader characteristic in the perpendicular plane indicated by Y, Y<1>. The dipole A is rotated continuously to cause the beam to rotate about its axis. As shown in Fig. 6, the transmitting and receiving dipoles Ae and Ar are rotated by the motor M so as to remain parallel. A pointer I is driven in synchronism with the aerials by the transmission system T. Echo signals received at R are applied to a neon lamp or similar luminous indicator L which illuminates the pointer I, whenever a signal is received, and thus by observing the directions in which the indicator is visible the aerial systems may be adjusted to train their axes upon the reflecting object, the indicator whereupon is continuously illuminated. The directive characteristics of the aerials may be rotated by other means, e.g. by rotating reflectors.
