Filed:

Feb 24, 2009

Appl. No.:

12/391940

Inventors:

James McNeill - Orlando FL, US
Todd MacKey - Satellite Beach FL, US
Tim Dyson - Melbourne FL, US

Assignee:

L-3 Communications CyTerra Corporation - Orlando FL

International Classification:

G01S 13/52
G01S 13/524

US Classification:

342 22, 342 28

Abstract:

A system and method for detecting entities based on movement can involve transmission circuitry configured to enable transmission of a stepped-frequency radar signal, an antenna, and receiving circuitry configured to generate data including information associated with frequency and phase shifts between the transmitted signal and the reflections of the transmitted signal. The system also can involve a processor configured to analyze the generated data to determine information associated with a moving object located at a side of a wall different than a side of the wall of which the system is located. The analyzing can involve compensating for the effect of motion of the system on the phase shifts between the transmitted signal and the reflections of the transmitted signal.

International Classification:

G01S 13/00

US Classification:

342 22, 342 28

Abstract:

A system and method for enabling transmission of a stepped-frequency radar signal can involve a first antenna and a second antenna. The system can also involve receiving circuitry configured to receive detected reflections from the antennas and to generate data including information associated with frequency and phase shifts. The system can further involve a processor configured to receive the generated data from the receiving circuitry and to analyze the generated data to determine information associated with a moving object located at a side of a wall opposite to the system by differentiating reflections of the transmitted signal detected with the first antenna from reflections of the transmitted signal detected with the second antenna.

Abstract:

A radar system may include an antenna, a waveform generator for generating a plurality of waveforms for different polarizations and/or having different frequency components, and a transmitter connected to the waveform generator for transmitting the plurality of waveforms via the antenna. Moreover, the radar system may also include a receiver connected to the antenna for receiving reflected signals from targets, and a processor for iteratively deconvolving the reflected signals to generate target data. More particularly, the radar system and targets may be relatively movable with respect to one another, and the processor may therefore store reflected signals over a length of relative movement and generate the target data based upon the stored signals to thus provide a synthetic aperture radar (SAR) system or an inverse SAR (ISAR) system.
