Patent number: 4565340Abstract: A guidance system for small spinning projectiles which is mechanically simple, has low power requirements, uses relatively unsophisticated electronics, and is capable of withstanding large gas pressures and accelerations. The system uses a one-piece fin assembly which is de-spun so that its guidance fins maintain a constant attitude with respect to the ground. The guidance fins and their hub can be nutated simultaneously and independently in two orthogonal planes by pivoting and translating a single control rod. The hub cooperates with the projectile body to reduce its base drag and thereby extend its range.Type: GrantFiled: August 15, 1984Date of Patent: January 21, 1986Assignee: Ford Aerospace & Communications CorporationInventor: William R.

Patent number: 4562439Abstract: An imaging radar seeker (8) for producing two-dimensional images of a target (2) is mounted on a missile (6) or other moving body, such as an automobile. A computer (40) directs the seeker (8) to operate sequentially in searching, tracking, and imaging modes. In the searching mode, a combination of circumferential rotation of antenna (12) of seeker (8) and frequency scanning of electromagnetic energy fed to antenna (12) enables seeker (8) to search for its target (2) over a conical field-of-view (16) or a wider, peripheral belt field-of-view (16). In the imaging mode, circumferential rotation of antenna (12) is stopped, and the tilt angle (A) of the linear array (32) of antenna (12) is stepped or continuously moved to compensate for radial movement of the radiated beam (14) caused by frequency stepping imparted by a frequency synthesizer (20). This keeps the beam (14) fixed in space and centered on target (2).Type: GrantFiled: December 13, 1982Date of Patent: December 31, 1985Assignee: Ford Aerospace & Communications CorporationInventors: Eduardo J.

Patent number: 4559541Abstract: A compact, low-profile broad-banded log-periodic antenna comprises a planar conductor (3) partially sandwiched by but electrically insulated from two substantially parallel spaced-apart ground planes (4, 8). The sandwich extends as far as an imaginary plane (15) that is orthogonal to conductor (3) and to the ground planes (4, 8). Conductor (3) comprises an alternating series of radiating loops (L(n)) and non-radiating transmission-line loops (L(j)). The non-radiating loops (L(j)'s) lie on the ground plane (4, 8) side of plane (15). The radiating loops (L(n)'s) lie on the other side of plane (15). Optional additional ground planes (6, 10) may be employed, in which case they lie in plane (15) and meet one of the primary ground planes (4 or 8, respectively) along a common edge. The length (d) of the loops (radiating or non-radiating), the spacing (D) between loops, and the height (h) and width (w) of the radiating loops (L(n)) are all scaled by a factor (S) which is less than 1 but greater than 0.Type: GrantFiled: August 19, 1983Date of Patent: December 17, 1985Assignee: Ford Aerospace & Communications CorporationInventor: Charles W.
