| Application No. | Application Title | Issue Date |
| 20080042896 | Using radar targets of opportunity to build a monopulse calibration table In a radar system, a monopulse calibration table is constructed from live targets of opportunity. A center of gravity or weighted average of normalized signals ΔV received at SUM and DIFF channels from a live target are used to determine the target's actual azimuth. Of... | 02/21/2008 |
| 20080030397 | METHOD FOR SOLVING TWO RF SIGNALS' ANGULAR POSITION A method for determining an angle for each of two RF signals at different frequencies and offset from each other. The average angle of a composite signal is obtained from the two RF signals over a frequency difference period by averaging the frequency difference period.... | 02/07/2008 |
| 20080030395 | Single bit pseudomonopulse tracking system for frequency agile receivers A system for generating a pseudomonopulse tracking error includes an antenna system (401) that generates a sum antenna beam and a difference antenna beam. The sum antenna beam has a pattern with a peak gain on the boresight axis, and the difference antenna beam h... | 02/07/2008 |
| 20070279276 | Pseudomonopulse tracking system with variable coupler and integrated LNA System for dynamically tracking a position of a target with an antenna in a communication system. The system includes an antenna system (410) configured for generating a sum and difference antenna pattern (201-1, 201-2). A sum RF channel (... | 12/06/2007 |
| 20070182622 | Method for locating multiple angle sources using a monopulse radar A monopulse radar tracking method which analyzes boresight error information provided a monopulse radar to determine a location for two targets. The monopulse radar tracking method analyzes the boresight error information to determine an angle of arrival for a dominant ... | 08/09/2007 |
| 20060238410 | REDUCING ANTENNA BORESIGHT ERROR Reducing antenna boresight error includes receiving radar pulses reflected from the ground, where pulses are emitted from the antenna of a radar system, reflected by the ground, and received by the antenna. The return pulses carry information about the ground. Measureme... | 10/26/2006 |
| 20060227039 | Instantaneous passive range finding A method and apparatus for use in determining the range in a single time sample from a platform to a target are disclosed. The method includes receiving radiation emanating from the target at two points on the platform in a common time sample; detecting the received rad... | 10/12/2006 |
| 20060077093 | REDUCING ANTENNA BORESIGHT ERROR Reducing antenna boresight error includes receiving radar pulses reflected from the ground, where pulses are emitted from the antenna of a radar system, reflected by the ground, and received by the antenna. The return pulses carry information about the ground. Measureme... | 04/13/2006 |
| 20050285778 | Axial deviation determining method for on-vehicle radar An on-vehicle radar and a method of determining an axial deviation of the radar using stationary objects free of erroneous determination are disclosed. The amount of axial deviation of the radar is determined from the calculated stationary object line based on the distr... | 12/29/2005 |
