Step Frequency High Resolution Radar

View page
US Patent:
8232907, Jul 31, 2012
Filed:
Aug 23, 2005
Appl. No.:
11/209336
Inventors:
Craig Aarseth - Massapequa NY, US
Robert Wahl - Kings Park NY, US
International Classification:
G01S 13/06
G01S 13/90
US Classification:
342 25R, 342132, 342196
Abstract:
The present invention is directed to an improved radar system that produces high range resolution while using existing narrow processing bandwidths and sampling rates to achieve a low cost radar product that is particularly useful for moving targets. The present invention uses a small number of closely spaced Linear Frequency Modulated Chirps. In one embodiment typically 2, 3, 4 chirps are used. Each frequency is sampled at a rate commensurate with the narrower bandwidth, corrected for motion, Time Aligned and combined to produce a single wide-band chirp but achieved using the lower sample rate commensurate with the narrower transmitted waveform.

Low Elevation Guidance System

US Patent:
47898640, Dec 6, 1988
Filed:
Apr 22, 1987
Appl. No.:
7/041166
Inventors:
Craig T. Aarseth - Massapequa NY
Assignee:
Eaton Corporation - Cleveland OH
International Classification:
G01S 116
US Classification:
342408
Abstract:
A guidance system for aircraft wherein a radio antenna on the ground transmits a beam that sweeps across an aircraft and the aircraft receives the beam and utilizes its amplitude waveform in determining the location of the aircraft from the station. At low elevation angles of the aircraft the portion of received waveform that includes significant amounts of signal reflected from the ground is used in only a preliminary manner. The more reliable, directly radiated, portions of the waveform are utilized to compute by least squares error, the median of a Gaussian beam shape. That median serves as an estimate of the time that the transmitting antenna was pointing directly at the aircraft.
