US Patent:

7978124, Jul 12, 2011

Filed:

Aug 3, 2009

Appl. No.:

12/462366

Inventors:

Carl D. Cook - La Habra CA, US
Scott E. Adcook - Irvine CA, US
Mena J. Ghebranious - Cerritos CA, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

G01S 13/52

US Classification:

342160, 342 22, 342161

Abstract:

Methods to quantify the amount of radial platform motion of a portable sensor are described. In an exemplary embodiment, the method uses the frequency domain phase data in the range bin corresponding to a large stationary object. A correction factor is computed and applied back into the time domain samples prior to processing by Doppler filters used to measure motion in the scene.

Assignee:

Raytheon Company - Waltham MA

International Classification:

G01S 13/538
G01S 13/52

US Classification:

342162, 342 22

Abstract:

A method and apparatus for sensing a target through a wall or obstruction by a Moving Target Indicator (MTI) radar sensor. In an exemplary embodiment, a series of radar pulses are transmitted at frequencies less than about 5 GHz. Radar return signals are received at a plurality of receive antenna array subapertures. The radar return signals are processed by a digital beamformer to form multiple beams. Target detection processing detects moving and stationary targets through a plurality of parallel target detection signal processing paths.
