US Patent:
7528765, May 5, 2009
Filed:
Mar 25, 2008

12/055199
Inventors:
Daniel L. Woodell - Cedar Rapids IA, US

Assignee:
Rockwell Collins, Inc. - Cedar Rapids IA
International Classification:
G01S 13/95
US Classification:
342 26B, 342 91
Abstract:
A weather radar system is coupled to an antenna. The weather radar system includes a processor for controlling pulses provided to the antenna and for processing return pulses received by the antenna. The processor is configured to vary a range resolution and loop gain relationship based on a data calculation. The weather radar system includes a processor for generating pulses and for processing return pulses received by the antenna. The processor generates high resolution data from the return pulses. The processor uses the high resolution data to perform high resolution radar analysis including removal of point and/or point-like target returns and reassembles the high resolution data to perform high gain radar analysis at lower resolutions.
Automatic Bright Band Detection And Compensation
US Patent:
7492304, Feb 17, 2009
Filed:
Jan 20, 2005
Appl. No.:
11/039753
Inventors:
Daniel L. Woodell - Robins IA, US
Roy E. Robertson - Marion IA, US
Roy E. Robertson - Marion IA, US
Assignee:
Rockwell Collins, Inc. - Cedar Rapids IA
International Classification:
G01S 13/95, G01S 7/28, G01S 13/00
US Classification:
342 26B, 342 26 R, 342175, 342195
Abstract:
A weather radar system has bright band detection and compensation. The weather radar system determines that high reflectivity in weather is a bright band and reduces an encoded return level from the bright band to compensate for it on a display. The weather radar system detects the presence of the bright band using an inference system that uses outside air temperature, aircraft altitude, and an assumed lapse rate to estimate the bright band location relative to the aircraft and uses antenna elevation to estimate bright band range to reduce the encoded radar return level on the display. The weather radar system may also detect the presence of the bright band using a detection system that uses radar estimates from normal reflectivity scan operation of the system. The weather radar system may also use an active detection process separate from a normal radar sampling process to detect the bright band.
