Patent Application Titled "Bistatic Synthetic Aperture Ladar System" Published Online

July 2, 2014



By a News Reporter-Staff News Editor at Defense & Aerospace Week -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventor Halmos, Maurice J. (Encino, CA), filed on December 6, 2012, was made available online on June 19, 2014.

The assignee for this patent application is Raytheon Company.

Reporters obtained the following quote from the background information supplied by the inventors: "A laser detection and ranging (LADAR) sensor, sometimes referred to as a ladar, uses laser beams to measure distances (or ranges) and instantaneous velocities. A ladar can be used to form images of scenes with a high degree of definition (e.g., 15 cm or better resolution at ranges greater than 1,000 meters). A ladar may be mounted on stationary objects and on vehicles such as airplanes, for example."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventor's summary information for this patent application: "In one aspect, ladar system includes a ladar transmitter system and a ladar receiver system configured to receive data from the transmitter. The ladar transmitter system and the ladar receiver system are disposed in a configuration forming a bistatic synthetic aperture ladar system.

"In another aspect, a ladar transmitter system includes a telescope, a laser and a communications module configured to communicate with a ladar receiver system to provide a frequency of the laser. The ladar transmitter system and the ladar receiver system are configured to be disposed in a configuration forming a bistatic synthetic aperture ladar system.

"In a further aspect, a ladar receiver system includes a telescope, a local oscillator (LO) laser, a heterodyne detector configured to receive signals from the telescope and the LO laser, electronics configured to process a signal from the heterodyne detector to image a target and a communications module configured to communicate with a ladar transmitter system to synchronize the LO laser with a laser of the ladar transmitter system. The ladar transmitter system and the ladar receiver system are configured to be disposed in a configuration forming a bistatic synthetic aperture ladar system.

BRIEF DESCRIPTION OF THE DRAWINGS

"FIG. 1 is a functional block diagram of a bistatic ladar system with respect to a target.

"FIG. 2A is a functional block diagram of an example of a ladar transmitter system of the bistatic ladar system of FIG. 1.

"FIG. 2B is a functional block diagram of an example of a ladar receiver system of the bistatic ladar system of FIG. 1.

"FIG. 3 is a flowchart of an example of a process to image the target using the bistatic ladar system of FIG. 1.

"FIG. 4 is a computer on which the process of FIG. 3 may be implemented."
