US Patent:

55348742, Jul 9, 1996

Filed:

Oct 7, 1992

Appl. No.:

8/160981

Inventors:

Larry Yujiri - Torrance CA
Michael S. Mussetto - Glendale CA
Gerald P. Uyeno - San Pedro CA

Assignee:

TRW Inc. - Redondo Beach CA

International Classification:

G01S 302

US Classification:

342351

Abstract:

A rotating mirror drum radiometer imaging apparatus. The apparatus generally comprises a two-sided mirror, a drum for securely supporting the two-sided mirror therein at an angle of preferably about 45 degrees relative to a longitudinal axis of symmetry extending through the drum, support walls for supporting the drum for rotational movement, and a motor and drive wheel for rotationally driving the drum. In the preferred embodiment the drum includes first and second cut-outs in a side surface thereof. The cut-outs are further spaced preferably about 180 degrees from each other about the longitudinal axis of symmetry and enable a transmitted signal to be alternately received therethrough by first and second sides of the two-sided mirror as the drum and mirror are concurrently rotated by the motor and drive wheel. A first antenna is disposed adjacent a first end of the drum and a second antenna is disposed adjacent a second end of the drum. The first and second antennas alternately receive the signal as the signal is alternately reflected from the first and second sides of the mirror as the mirror is driven rotationally.

A rotating mirror drum radiometer imaging apparatus. The apparatus generally comprises a two-sided mirror, a drum for securely supporting the two-sided mirror therein at an angle of preferably about 45 degrees relative to a longitudinal axis of symmetry extending through the drum, support walls for supporting the drum for rotational movement, and a motor and drive wheel for rotationally driving the drum. In one embodiment the drum includes first and second cut-outs in a side surface thereof. The cut-outs are further spaced preferably about 180 degrees from each other about the longitudinal axis of symmetry and enable a transmitted signal to be alternately received therethrough by first and second sides of the two-sided mirror as the drum and mirror are concurrently rotated by the motor and drive wheel. A first antenna is disposed adjacent a first end of the drum and a second antenna is disposed adjacent a second end of the drum. The first and second antennas, either dish antennas or an imaging array, alternately receive the signal as the signal is alternately reflected from the first and second sides of the mirror as the mirror is driven rotationally.
